ABSTRACT

Systemic sclerosis is an immunological disorder characterized by tissue fibrosis and multi-organ dysfunction.1 The accompanying images exhibit electrocardiographic changes in severe systemic sclerosis. Advanced 3:1 atrioventricular block, best observed in Lead Vi, suggests extensive fibrosis of the conduction system (Image A). While one P wave is buried in the T wave (black arrows), two are evident (red arrows) along the isoelectric line. Bradyarrhythmia related prolonged QT interval, best measured in Lead II represents increased risk for torsades-de-pointes, a polymorphic ventricular tachyarrhythmia. Additionally, right bundle branch block with giant T wave inversions (T wave depth > 10 mm) in precordial leads V2- 4 suggests pulmonary hypertension. Post-induction the rhythm abruptly changes to torsades-de-pointes (Image B) necessitating defibrillation.


La esclerosis sistémica es un trastorno inmunológico caracterizado por fibrosis tisular y disfunción multiorgánica. 1 Las imágenes adjuntas muestran cambios electrocardiográficos en la esclerosis sistémica grave. El bloqueo auriculoventricular avanzado 3: 1, que se observa mejor en la derivación VI, sugiere una fibrosis extensa del sistema de conducción ( Imagen A ).Mientras que una onda P está enterrada en la onda T (flechas negras), dos son evidentes (flechas rojas) a lo largo de la línea isoeléctrica. El intervalo QT prolongado relacionado con bradiarritmia, mejor medido en la derivación II, representa un mayor riesgo de torsades-de-pointes, una taquiarritmia ventricular polimórfica. Además, el bloqueo de la rama derecha del haz con inversiones de la onda T gigante (profundidad de la onda T> 10 mm) en las derivaciones precordiales V2- 4 sugiere hipertensión pulmonar. Después de la inducción, el ritmo cambia abruptamente a torsades-de-pointes ( Imagen B ), lo que requiere desfibrilación.

ABSTRACT

Un gossypiboma, oblitoma o textiloma se define como todo cuerpo extraño olvidado en el interior de un paciente durante una intervención quirúrgica. Representa una complicación posquirúrgica poco frecuente pero de consecuencias potencialmente graves. En general, se manifiesta con cuadros clínicos variables: una masa o pseudotumor, sangrados, fiebre, dolor, varios meses o años después de la cirugía original. También puede ser un hallazgo accidental. Describimos el caso clínico de una paciente con un gossypiboma vinculado a una cirugía cardíaca que se realizó 40 años antes al cuadro clínico actual, que se presenta con arritmia ventricular maligna.


A gossypiboma, oblitoma or textiloma is defined as a surgical object left in the interior of the body after surgery. It represents an uncommon but potentially life threatening post-surgery complication. Clinical manifestations are variable and depend on location, relations and size, from pseudo-tumoral masses, bleeding, fever, pain and other nonspecific presentations. The onset of symptoms is unpredictable, occurring from months or years after surgery. Patients may course asymptomatically and be diagnosed incidentally as an imaging finding. We describe a case of a patient with gossypiboma diagnosed 40 years after undergoing cardiac surgery, who presented with a malignant ventricular arrhythmia.

ABSTRACT

Objetivo: Caracterizar o perfil clínico dos pacientes submetidos à cirurgia cardíaca no perioperatório e descrever o acompanhamento após 30 dias da alta hospitalar. Método: Estudo retrospectivo, com amostra de 54 pacientes, de ambos os sexos, com idade ≥18 anos, submetidos à cirurgia cardíaca. As variáveis analisadas foram: sociodemográficas, clínicas e relacionadas ao perioperatório e seguimento em 30 dias. Resultados: A média de idade dos pacientes foi de 65,5±15 anos; a maioria do sexo masculino (79,6%). Fatores de risco mais prevalentes: hipertensão (72,2%), dislipidemia (48,1%) e cardiopatia isquêmica (31,5%). Os procedimentos valvares tiveram maior prevalência (50,0%). A complicação mais prevalente no pós-operatório foi arritmia (18,5%). No pós-alta, o uso das estatinas predominou (78,4%), seguido de antiagregante plaquetário (50,9%) e anticoagulante (31,3%). Após 30 dias da alta hospitalar, houve 11,7% de readmissões, sendo a infecção respiratória/derrame pleural e a infecção de sítio cirúrgico as principais causas de reinternação. Conclusão: Os pacientes cardícos foram na maioria homens, idosos e que apresentavam comorbidades; arritmia foi a principal complicação após a cirúrgia. A incidência de readmissão após 30 dias da alta foi relacionada a comprometimentos pulmonares e infecciosos.


Objective: To characterize the clinical profile of patients who underwent cardiac surgery in the perioperative period and describe the follow-up after 30 days of hospital discharge. Method: Retrospective study, with a sample of 54 patients, both male and female, aged ≥18 years. The analyzed variables were: sociodemographic, clinical and those related to the perioperative period and 30-day follow-up. Results: The mean age of patients was 65.5±15 years; most were male (79.6%). The most prevalent risk factors were: hypertension (72.2%), dyslipidemia (48.1%) and ischemic heart disease (31.5%). Valve procedures had higher prevalence (50.0%). The most prevalent complication in the postoperative period was arrhythmia (18.5%). At post­discharge, statins (78.4%) were the most prevalent medication, followed by antiplatelet agents (50.9%) and anticoagulants (31.3%). After 30 days of hospital discharge, the percentage of readmission was 11.7%, being the main causes of readmission respiratory infection/pleural effusion and surgical site infection. Conclusion: Surgical patients were mostly elderly men who had comorbidities; arrhythmia was the main complication found after surgery. The incidence of readmission 30 days after discharge was related to pulmonary complications and infections.

ABSTRACT

Early recognition and treatment for early warning electrocardiogram (ECG) of sudden death are very important to prevent and treat malignant arrhythmia and sudden death. Previous studies have found that R-on-T and T wave alternation, and QT interval prolongation are closely related to malignant arrhythmia or sudden death, which are included in the critical value of ECG.By analyzing the ECG characteristics of 4 patients with sudden death, we found that although the causes of the patients were different, there were transient prolongation of QT interval after premature contraction in 12 lead ECG, followed by malignant arrhythmia or sudden death. Thus, we thought that the transient prolongation of QT interval after premature contraction had a high value for warning malignant arrhythmia or sudden death. This phenomenon should be paid enough attention to reduce the risk of sudden death.

ABSTRACT

SUMMARY OBJECTIVE: Different parameters on electrocardiograms (ECG) have been investigated to predict arrhythmia and mortality in patients with acute pulmonary embolism (APE). The acute effect of thrombolytic therapy (TT) on these parameters has not been investigated yet. METHODS: We examined the data of 83 patients who were evaluated as high-risk APE and discharged from the hospital after TT. First, the high-risk APE patients' ECGs were compared with healthy control subjects (n = 55). After their admission and 24 hours later, the ECGs of patients with APE were compared. Heart rate, P-wave morphology, QRS duration, QT distance, Tp-e, and the index of cardiac electrophysiological balance (iCEB) were analyzed. RESULTS: Although P maximum was not different between the groups' ECGs, heart rate, QT, QTc (corrected QT) interval, Tp-e intervals, Tp-e/QT ratio, and P wave dispersion were significantly higher in the APE group ( P values < 0.031). iCEB or iCEBc (corrected iCEB) values were lower in APE group ( P < 0.001). After TT, we determined a decrease in heart rate, Tp-e interval, and Tp-e/QT ratio ( P < 0.001). Although we detected a decrease in the QT and QTc interval and QT dispersion (QTd), QTd had no statistical significance (respectively P -value 0.013, 0.029, and 0.096). The iCEB and iCEBc levels were lower after TT ( P -value was 0.035 and 0.044 respectively). CONCLUSION: The QT, QTc, Tp-e interval, Tp-e/QTc ratio, iCEB, and iCEBc values significantly decreased after TT. It may be thought that effective TT causes partial improvement in ventricular repolarization in an early period.


RESUMO OBJETIVO: Diferentes parâmetros de eletrocardiograma (ECG) têm sido investigados para predizer mortalidade e arritmia em pacientes com embolia pulmonar aguda (EPA). O efeito agudo da terapia trombolítica (TT) nesses parâmetros ainda não foi investigado. MÉTODOS: Examinamos os dados de 83 pacientes avaliados com EPA de alto risco e que receberam alta hospitalar após TT. Primeiramente, comparamos os ECGs dos pacientes com EPA de alto risco com os de indivíduos saudáveis (n = 55). Os ECGs dos pacientes com EPA foram comparados logo após a internação e 24 horas mais tarde. A frequência cardíaca, a morfologia da onda P, a duração do QRS, o intervalo QT, Tp-e e o índice de equilíbrio eletrofisiológico cardíaco (iCEB) foram analisados. RESULTADOS: Embora o valor máximo de P não tenha sido diferente entre os grupos no ECG, a frequência cardíaca, QT, intervalo QTc (QT corrigido), intervalos Tpe, razão TP-e/QT e dispersão da onda P foram significativamente mais elevados no grupo de EPA (valores de P < 0,031). Os valores do iCEB ou iCEBc (iCEB corrigido) foram inferiores no grupo de APE (P < 0,001). Após a TT, observamos uma diminuição da frequência cardíaca, do intervalo TP-e e da razão TP-e/QT ( P < 0,001). Apesar de termos observado uma diminuição do intervalo QT e QTc e da dispersão do QT (QTd), o valor de QTd não apresentou uma diferença estatisticamente significativa (respectivamente, valor de P 0,013, 0,029 e 0,096). Os níveis do iCEB e iCEBc foram menores após a TT (valor de P 0,035 e 0,044, respectivamente). CONCLUSÃO: Os valores de QT, QTc, intervalo Tp-e, razão Tp-e/QTc, iCEB e iCEBc diminuíram significativamente após TT. Pode-se concluir que a TT eficaz causa uma melhora parcial da repolarização ventricular no período inicial.

ABSTRACT

Resumen: La intoxicación escombroide es ocasionada por el consumo de ciertos tipos de pescado (de la familia Scombridae), comúnmente el atún, los cuales acumulan grandes concentraciones de histamina cuando los procedimientos de refrigeración son inadecuados, ocasionando en quienes los consumen síntomas muy similares a los de una alergia alimentaria, por lo que es frecuente que no se diagnostique correctamente. Generalmente, los síntomas desaparecen en pocas horas y no suelen ser graves, excepto algunos casos descritos en la literatura especializada, de hipotensión, broncoespasmo, dificultad respiratoria, taquicardia supraventricular e, incluso, infarto agudo de miocardio. Este fue, precisamente, el caso de una mujer que ingresó al servicio de urgencias de un hospital de tercer nivel de Medellín a los pocos minutos de haber ingerido atún con una sintomatología típica de la intoxicación, pero con taquicardia supraventricular, una de sus manifestaciones graves y atípicas.


Abstract: Scombroid poisoning is caused by the consumption of certain types of fish (from the Scombridae family), especially tuna. Due to inadequate refrigeration procedures, these fish have high levels of histamine which generate symptoms similar to those of a food allergy in their consumers, so it is frequently underdiagnosed. It is self-limited in a few hours and the symptoms are usually not serious, except for specific cases reported in the literature of hypotension, bronchospasm, respiratory distress, tachyarrhythmias, and even acute myocardial infarction. We report here the case of a woman admitted to the emergency department of a third level hospital in Medellín a few minutes after eating tuna with the typical symptoms of intoxication, as well as tachyarrhythmias, a serious and atypical manifestation.

ABSTRACT

Resumen Hasta hace algunas décadas los tumores cardiacos tenían solo un interés académico dada su baja tasa de presentación; sin embargo, con el advenimiento del baipás cardiopulmonar, el manejo quirúrgico comienza a ser posible y, más recientemente, junto con la investigación farmacológica, contribuyen al desarrollo de nuevas estrategias de tratamiento para estos pacientes. La incidencia estimada de los tumores cardiacos es baja y tiene un comportamiento generalmente benigno y manifestaciones clínicas inespecíficas. Estos tumores en la edad pediátrica se asocian a esclerosis tuberosa, una enfermedad de patrón de herencia autosómica dominante que se caracteriza por una alteración en la diferenciación y multiplicación celular (hamartomas) en diferentes sistemas. Desde el punto de vista cardiaco, el grado de morbilidad está condicionado por el tamaño y la localización tumoral dentro de la cavidad, y tiene riesgo de obstruir los tractos de salida ventriculares, alterar la función valvular o producir trastornos de conducción. Algunos pacientes solo requieren seguimiento clínico durante el transcurso de su vida, pero existe la posibilidad de regresión tumoral; otros se benefician de una resección quirúrgica por su impacto hemodinámico o alteraciones del ritmo cardiaco. Sin embargo, no todos son candidatos quirúrgicos, en cuyo caso el manejo con inhibidores m-TOR ha surgido como una alternativa terapéutica. Se presenta el caso de tres neonatos con esclerosis tuberosa y rabdomioma cardiaco, diagnosticados en etapa prenatal, a quienes se les realizó un abordaje terapéutico individualizado, basado en las opciones actuales disponibles para este grupo de pacientes.


Abstract Up to a few decades ago, cardiac tumours were only of academic interest given their low presentation rate. However, with the advances in cardiopulmonary, surgical management began to be possible, and more recently, they contribute to the development of new treatment strategies for these patients. The estimated incidence of cardiac tumours is low and are generally benign with non-specific clinical signs and symptoms. In paediatrics, these tumours are associated with tuberous sclerosis, a disease with a dominant autosomal inheritance pattern, which is characterised by an alteration in cell differentiation and multiplication (hamartomas) in different systems. From a cardiac point of view, the morbidity level is determined by the size and location of the tumour within the cavity, the risk of obstructing ventricular outflow tracts, alterations in valvular function, and conduction disorders. Some patients only require clinical follow-up all their lives, as there is the risk of tumour regression. Others may benefit from surgical resection due to its haemodynamic impact or changes in cardiac rhythm. However, not everyone is a candidate for surgery, in which case, management with m-TOR inhibitors has emerged as a therapeutic alternative. The case is presented on three neonates with tuberous sclerosis and a cardiac rhabdomyoma, diagnosed in the prenatal stage. An individualised therapeutic approach was made based on the current options available for this group of patients.

ABSTRACT

ABSTRACT Objective: to assess the health-related quality of life of patients with a permanent cardiac pacemaker. Method: descriptive, observational, cross-sectional study conducted in the arrhythmia outpatient unit of a university hospital located in the interior of São Paulo, Brazil. The consecutive and non-probabilistic sample was composed of both sexes, older than 29 years old, having a pacemaker for at least one month. Those lacking the cognitive condition to answer the questionnaires, as well as those with dyspnea, weakness, or fatigue at the time the instruments were applied, or with an implantable cardioverter defibrillator, were excluded. The generic instrument Medical Outcomes Study 36 - Item Short-Form Health Survey, composed of 36 questions distributed into eight domains along with the specific instrument Assessment of Quality of Life and Related Events, composed of 20 questions distributed into three domains, were used to assess health-related quality of life. Results: 88 patients participated; most were men, had a partner, and were aged 64.3 (±13) years old on average. The domains from the Medical Outcomes Study 36 that obtained the highest means, that is, were the best-rated, were Social Functioning (78.1; ±26.8) and Emotional Well-Being (68.2; ±23.9), while the lowest means were obtained by Physical Health (48.2; ±41.4) and Physical Functioning (58.5; ±27.9). In regard to the Assessment of Quality of Life and Related Events, the Arrhythmia domain had the highest mean and best quality of life (78.2; ±20.7), while the lowest mean was Dyspnea (71.1; ±26.8). Conclusion: the patients gave the highest health-related quality of life ratings in regard to mental domains and the lowest ratings for the physical domains.

ABSTRACT

INTRODUÇÃO: As ectopias atriais podem manifestar-se de diversas formas desde a ausência de sintomas até síncope. Descrevemos um caso de bigeminismo atrial bloqueado com prolongamento do intervalo QT e consequente Torsades de Pointes. Relato de caso: Paciente do sexo feminino, 75 anos, foi admitida no serviço de pronto atendimento devido a queixa de episódios recorrentes de síncope em posição sentada após sensação inespecífica de mal-estar, dispneia e turvação visual associado a liberação esfincteriana. ECG na admissão revelou ritmo sinusal e ectopias supraventriculares frequentes, motivo pelo qual iniciou-se terapia com amiodarona. Holter de 24h demonstrou bigeminismo atrial bloqueado e prolongamento do intervalo QT seguido por episódios de Torsade de Pointes e fibrilação ventricular. Realizado implante de marcapasso provisório seguido por ablação do foco arritmogênico em região de anel triscuspídeo. A paciente evoluiu com melhora da sintomatologia e Holter de controle demonstrou ausência de arritmias.

ABSTRACT

Resumo Fundamento: Não há estudos avaliando o intervalo Tpico-Tfim (Tpe), a relação Tpe/QT e a relação Tpe/QTc para avaliar arritmias cardíacas em pacientes com COVID-19. Objetivo: Visamos investigar se há alterações nos intervalos QT, QTc e Tpe e nas relações Tpe/QT e Tpe/QTc em pacientes com COVID-19. Métodos: O estudo incluiu 90 pacientes com infecção por COVID-19 e 30 controles saudáveis pareados por sexo e idade. Foram aferidos os intervalos QT, QTc e Tpe e as relações Tpe/QT e Tpe/QTc. Os participantes incluídos no estudo foram divididos nos seguintes 4 grupos: controles saudáveis (grupo I), pacientes com COVID-19 sem pneumonia (grupo II), pacientes com COVID-19 e pneumonia leve (grupo III) e pacientes com COVID-19 e pneumonia grave (grupo IV). Significância estatística foi definida por valor p < 0,05. Resultados: Verificou-se que a frequência cardíaca basal, a presença de hipertensão e diabetes, a contagem de leucócitos, o nitrogênio ureico no sangue, a creatinina, o potássio, o aspartato aminotransferase, a alanina aminotransferase, o NT-proBNP, a proteína C reativa de alta sensibilidade, o dímero-D, a TncI-as, o intervalo Tpe, a relação Tpe/QT e a relação Tpe/QTc aumentaram do grupo I para o grupo IV e foram significativamente mais altos em todos os pacientes do grupo IV (p < 0,05). A pressão arterial sistólica, a hemoglobina e os níveis de cálcio eram menores no grupo IV e significativamente menores em comparação com os demais grupos (< 0,05). Os intervalos QT e QTc eram semelhantes entre grupos. Determinou-se que os níveis elevados de frequência cardíaca, cálcio, dímero-D, NT-proBNP e PCR-as eram significativamente relacionados a Tpe, Tpe/QT e Tpe/QTc. Conclusões: Em pacientes com COVID-19 e pneumonia grave, o intervalo Tpe, a relação Tpe/QT e a relação Tpe/QTc, que estão entre os parâmetros de repolarização ventricular, foram aumentados, sem prolongação dos intervalos QT e QTc. A partir deste estudo, não podemos definitivamente concluir que as alterações eletrocardiográficas observadas estão diretamente relacionadas à infecção por COVID-19 ou à inflamação, mas sim associadas a cenários graves de COVID-19, que podem envolver outras causas de inflamação e comorbidades.


Abstract Background: There is no study evaluating the Tpeak-Tend (Tpe) interval, Tpe/QT ratio, and Tpe/QTc ratio to assess cardiac arrhythmias in patients with COVID-19. Objective: We aimed to examine whether there is a change in QT, QTc, Tpe interval, Tpe/QT ratio, and Tpe/QTc ratio in patients with COVID-19. Methods: The study included 90 patients with COVID-19 infection and 30 age-and-sex-matched healthy controls. QT, QTc, Tpe interval, Tpe/QT ratio, and Tpe/QTc ratio were measured. The participants included in the study were divided into the following 4 groups: healthy controls (group I), patients with COVID-19 without pneumonia (group II), patients with COVID-19 and mild pneumonia (group III), and patients with COVID-19 and severe pneumonia (group IV). Statistical significance was set at p < 0.05. Results: It was found that baseline heart rate, presence of hypertension and diabetes, white blood cell count, blood urea nitrogen, creatinine, potassium, aspartate aminotransferase, alanine aminotransferase, NT-proBNP, high sensitive C reactive protein, D-dimer, hs-cTnI, Tpe, Tpe/QT, and Tpe/QTc increased from group I to group IV, and they were significantly higher in all patients in group IV (p < 0.05). Systolic-diastolic blood pressure, hemoglobin, and calcium levels were found to be lowest in group IV and significantly lower than in other groups (< 0.05). QT and QTc intervals were similar between groups. It was determined that increased heart rate, calcium, D-dimer, NT-proBNP and hs-CRP levels were significantly related to Tpe, Tpe/QT, and Tpe/QTc. Conclusions: In patients with COVID-19 and severe pneumonia, Tpe, Tpe/QT ratio, and Tpe/QTc ratio, which are among ventricular repolarization parameters, were found to be increased, without prolonged QT and QTc intervals. In this study, we cannot definitively conclude that the ECG changes observed are directly related to COVID-19 infection or inflammation, but rather associated with severe COVID-19 scenarios, which might involve other causes of inflammation and comorbidities.

ABSTRACT

Resumen Introducción: La falla cardíaca es un problema de salud pública, cuya prevalencia aumenta con la edad. Hasta el 50% de los casos tiene fracción de eyección preservada. Pocos estudios evalúan arritmias en este tipo de población. Se conoce una asociación con fibrilación auricular, pero se ignora qué otro tipo de arritmias pueden estar presentes. Objetivo: Describir arritmias por medio de monitorización Holter de 24 horas en pacientes con disfunción diastólica. Materiales y métodos: Se realizó un estudio observacional, descriptivo y retrospectivo, en el que se evaluaron y compararon los parámetros de la monitorización Holter de 24 horas en pacientes con disfunción diastólica, provenientes de un solo centro y residentes en Medellín, durante el año 2017. Resultados: 67 pacientes tenían disfunción diastólica; la mayoría correspondió a mujeres (65.7%). El promedio de edad fue 71 años, el índice de masa corporal fue de 26,8 y las comorbilidades más frecuentes fueron hipertensión arterial (68,7%), fibrilación auricular (19,4%) y enfermedad coronaria (19,4%). El promedio de fracción de eyección fue de 58%; el 67,2% tenía disfunción diastólica tipo I y el promedio del volumen de la aurícula izquierda fue de 33 ml/m2. Las arritmias más frecuentes fueron taquicardia atrial no sostenida (40,3%), fibrilación auricular (10,4%), taquicardia ventricular monomórfica (7,5%) y taquicardia por reentrada intranodal (1.5%). Se presentó bloqueo AV de primer grado (22,4%) y bloqueo sinoatrial (1,5%). El promedio de variabilidad de la frecuencia cardíaca fue 126.23. Conclusiones: En pacientes con disfunción diastólica tipo I y II se documentaron varios tipos de arritmias más allá de la fibrilación auricular. No hubo alteraciones en la variabilidad de la frecuencia cardíaca y tampoco en el tiempo de QTc. Dada la existencia de trasfondo fisiopatológico común, se debe evaluar en estudios futuros la relación entre arritmias y disfunción diastólica, además de su potencial tratamiento y modificación de su curso clínico.


Abstract Introduction: Heart failure is a public health problem, with a prevalence that increases with age. Up to 50% of cases have a preserve ejection fraction. Few studies have evaluated arrhythmias in this population type. It is known that there is an association with atrial fibrillation, but other types of arrhythmias that could be present are ignored. Objective: To describe arrhythmias using 24 hour Holter monitoring in patients with diastolic dysfunction. Materials and methods: An observational, descriptive, and retrospective study was performed in which the parameters from 24 hour Holter monitoring were evaluated and compared in patients with diastolic dysfunction from a single centre and resident in Medellin, during the year 2017. Results: A total of 67 patients had diastolic dysfunction, in which the majority (65.7%) were women. The mean age was 71 years, with a mean body mass index of 26.8. The most frequent comorbidities were arterial hypertension (68.7%), atrial fibrillation (19.4%), and coronary disease (19.4%). The mean ejection fraction was 58%; 67.2% had a type I diastolic dysfunction, and the mean atrial volume was 33 ml/m2. The most common arrhythmias were discontinuous atrial flutter (40.3%), atrial fibrillation (10.4%), monomorphic ventricular tachycardia (7.5%) and nodal re-entrant tachycardia (1.5%). First degree AV block (22.4%) and sinoatrial block (1.5%) were observed. The mean heart rate variability was 126.23. Conclusions: Several types of arrhythmias other than atrial fibrillation were documented in patients with type I and type II diastolic dysfunction. There were no changes in the heart rate variability or in the QTc time. Given the existence of a common pathophysiological background, further studies are needed in order to evaluate the relationship between arrhythmias and diastolic dysfunction, as well as any potential treatment and modification of its clinical course.

ABSTRACT

Introducción: Las enfermedades cerebrovasculares son la tercera causa de muerte y la primera de invalidez en el mundo. Objetivo: Medir las asociaciones entre los ictus cerebrovasculares y sus factores de riesgo. Métodos: Se realizó un estudio descriptivo, la serie estuvo conformada por 904 pacientes con diagnóstico al ingreso de enfermedad cerebrovascular, en el período comprendido entre junio 2017 a junio 2018, en el Hospital Militar Central "Dr. Carlos J. Finlay". Se analizaron las formas clínicas de enfermedad cerebrovascular, a partir de las variables edad, sexo, hábito de fumar, alcoholismo, hipertensión arterial, diabetes mellitus, hipercolesterolemia e hipertrigliceridemia. Se utilizaron como medidas de resumen, las frecuencias absolutas y relativas. Resultados: El 54,7 por ciento de los pacientes eran mayores de 70 años y el 58,7 por ciento del sexo masculino. El hábito de fumar se constató en el 87,7 por ciento de pacientes con ictus aterotrombótico y en el 89,2 por ciento de los que tuvieron hemorragias intraparenquimatosas y el alcohol en el 64,6 por ciento de los pacientes con hemorragias intraparenquimatosas. Más del 80 por ciento de los pacientes con ictus isquémicos y hemorrágicos, eran hipertensos. El ictus cardioembólico se asoció en el 91,9 por ciento, con arritmia cardiaca. Conclusiones: La enfermedad cerebrovascular predominó por encima de los 70 años y del sexo masculino. Los ictus isquémicos son más frecuentes que los hemorrágicos. La hipertensión arterial y la diabetes mellitus fueron los factores de riesgo más frecuentes, tanto en los ictus isquémicos como hemorrágicos(AU)


Introduction: Cerebrovascular disease is the third leading cause of death and the first cause of disability in the world. Objective: To measure the associations between cerebrovascular strokes and their risk factors. Methods: A descriptive study was carried out, the series was made up of 904 patients diagnosed upon admission of cerebrovascular disease, in the period from June 2017 to June 2018 at the Hospital Militar Central Dr. Carlos J. Finlay. The different clinical forms of cardiovascular diseases were analyzed based on the variables age, sex, smoking, alcoholism, high blood pressure, diabetes mellitus, hypercholesterolemia and hypertriglyceridemia. Absolute and relative frequencies were used as summary measures. Results: 54.7 percent of patients were older than 70 years and 58.7 percent were male. Smoking was found in 87.7 percent of atherothrombotic stroke and in 89.2 percent of intraparenchymal hemorrhages and alcohol in 64.6 percent of intraparenchymal hemorrhages. More than 80 percent of the patients with ischemic and haemorrhagic stroke were hypertensive, and cardioembolic stroke was associated in 91.9 percent with cardiac arrhythmia. Conclusions: Cerebrovascular disease was predominant over 70 years old and male. Ischemic strokes are more frequent than hemorrhagic ones. High blood pressure and diabetes mellitus were the most frequent risk factors for both ischemic and hemorrhagic strokes(AU)

ABSTRACT

ABSTRACT: Electrocardiographic markers have been used in people to classify arrhythmogenic risk. The aims of this study were to investigate electrocardiographic markers of conduction and repolarization in Boxers and non-Boxer dogs, and compare such findings between groups. Ten-lead standard electrocardiograms of Boxer dogs and non-Boxers recorded from 2015 to 2018 were retrospectively reviewed. Dogs >/ 4 years of age and weighing > 20kg were included. Animals with valvular insufficiencies, congenital cardiopathies, cardiac dilation, suspected systolic dysfunction, biphasic T-wave, bundle branch blocks, and those receiving antiarrhythmics were excluded. Electrocardiographic markers of conduction, QRS duration (QRSd) and dispersion (QRSD), and repolarization (corrected QT interval, Tpeak-Tend, JT and JTpeak), as well as derived indices, were measured. Two hundred dogs met the inclusion/exclusion requirements, including 97 Boxers (8.1±2.5 years old; 30±7kg) and 103 non-Boxer (8.8±2.5 years old, 30±8kg). QRSd and QRSD, and repolarization markers in lead II and left precordial lead V4 were considered similar between groups. Dispersion of late repolarization on lead rV2, Tpeak-Tend interval, was considered longer in Boxers (45±8ms vs 38±10ms, P=0.01). The Tpeak-Tend/JTpeak and the JTpeak/JT also differed between groups. Our results indicate that the dispersion of myocardial late repolarization in lead rV2 is slower in Boxers than other dog breeds.(AU)


Marcadores eletrocardiográficos têm sido estudados em seres humanos para estratificação do risco arritmogênico. Os objetivos deste estudo foram investigar os marcadores eletrocardiográficos de condução e repolarização miocárdica em Boxers e em cães de outras raças, e comparar tais resultados entre os grupos. Para tal, a eletrocardiografia convencional de 10 derivações registradas de 2015 a 2018 foram avaliadas de maneira retrospectiva. Cães com idade igual ou superior a 4 anos e pesando > 20kg foram incluídos. Animais com insuficiência valvar, cardiopatias congênitas, dilatação cardíaca, suspeita de disfunção sistólica, onda T bifásica, bloqueio(s) de ramo(s), ou aqueles que recebiam antiarrítmicos foram excluídos. Variáveis eletrocardiográficas de condução, como a duração e dispersão do complexo QRS (QRSd e QRSD, respectivamente), e repolarização (intervalo QT corrigido, Tpico-Tfinal, JT e JTpico), bem como índices derivados, foram mensurados. Duzentos cães que se adequaram aos critérios de inclusão/exclusão foram incluídos, 97 Boxers (8,1±2,5 anos; 30±7kg) e 103 não Boxers (8,8±2,5 anos; 30±8kg). O QRSd e o QRSD, e os marcadores de repolarização nas derivações II e V4 foram similares entre os grupos. O marcador de dispersão da repolarização tardia na derivação rV2, Tpico-Tfinal, foi considerado mais longo no Boxers (45±8ms vs 38±10ms, P=0.01). O Tpico-Tfinal/JTpico e o JTpico/JT também diferiram entre os grupos. Nossos resultados indicam que a dispersão da repolarização miocárdica tardia na derivação precordial direita, rV2, é mais lenta no Boxer do que nas outras raças.(AU)

ABSTRACT

La arritmia y taquicardia son muy comunes en las embarazadas, aunque el bloqueo espinal pueda ser una técnica anestésica segura, la taquicardia grave, la parada cardiaca y otras arritmias son relatadas durante las prácticas de raquianestesia. La bupivacaina y levobupivacaina pueden aumentar el intervalo PR y la duración del QRS y prolongar la conducción cardiaca. La dexmedetomidina tiene propiedades simpaticolíticas, sedativas, estabilidad respiratoria sin depresión ventilatoria, amnésicas y analgésicas, los efectos adversos de la dexmedetomidina son la hipertensión inicial, hipotensión, naúseas, bradicardia, fibrilación atrial, edema pulmonar, oliguria y sed. Paciente de 33 años de edad con embarazo de 39,2 sem. Sin antecedentes patológicos. Recibe anestesia espinal y a los 10 min bradicardica de 39 corregida con atropina y posterior con arritmia sinusal. En conclusión, la presencia de arritmias cardiacas puede deberse a varios factores, es trascendental la vigilancia y monitoreo continuo del electrocardiograma para reconocer y corregir de manera oportuna.


Arrhythmia and tachycardia are very common in pregnant women, although spinal block may be a safe anesthetic technique, severe tachycardia, cardiac arrest and other arrhythmias are reported during spinal anesthesia practices. Bupivacaine and levobupivacaine can increase the PR interval and the duration of QRS and prolong cardiac conduction. Dexmedetomidine with sympatholytic, sedative, respiratory stability without ventilatory depression, amnesic and analgesic properties, the adverse effects of dexmedetomidine are initial hypertension, hypotension, nausea, bradycardia, atrial fibrillation, pulmonary edema, oliguria and thirst. 33-year-old patient with a pregnancy of 39.2 weeks. No pathological history she received spinal anesthesia and at 10 min bradycardia of 39 corrected with atropine and later with sinus arrhythmia. In conclusion, the presence of cardiac arrhythmias can be due to several factors, the continuous monitoring and monitoring of the electrocardiogram to recognize and correct in a timely manner is transcendental.

ABSTRACT

Resumen: Las taquicardias paroxísticas supraventriculares son arritmias frecuentes y producen importante morbilidad. El estudio electrofisiológico permite hacer el diagnóstico su mecanismo para luego realizar la ablación. El diagnóstico no siempre es sencillo y se debe recurrir a múltiples observaciones y maniobras para alcanzarlo. En la siguiente revisión se discuten los principales criterios usados para el diagnóstico del mecanismo de estas taquicardias durante un estudio electrofisiológico.
