Resumo Fundamento Não existem estudos randomizados comparando a manutenção do ritmo sinusal após ablação por cateter (AC) em relação ao tratamento com fármacos antiarrítmicos (AA) em pacientes idosos portadores fibrilação atrial (FA) paroxística. Objetivos Comparar os resultados clínicos do isolamento das veias pulmonares (VPs) com o cateter PVAC Gold de segunda geração com o uso de AA em idosos com FA paroxística sintomática, recorrente, apesar do uso de fármacos AA. Métodos Sessenta pacientes com FA paroxística ≥ 65 anos e sem cardiopatias estruturais foram randomizados para duas formas de tratamento: grupo 1: AC e grupo 2: AA. O desfecho primário foi a taxa livre de recorrência de FA após pelo menos um ano de seguimento. Os desfechos secundários foram: progressão para formas persistentes de FA, impacto na qualidade de vida (QVFA) e complicações. O nível de significância adotado na análise estatística foi de 5% (p<0,05). Resultados A taxa livre de recorrência de FA foi de 80% (10% com amiodarona) no grupo AC, após 1,3 procedimentos por paciente e de 65% no grupo AA (60% com amiodarona), (p = 0,119) num seguimento médio de 719 dias (Q1: 566; Q3: 730). A taxa livre de FA persistente foi de 83,4% no grupo AC e de 67,7% no grupo AA (p = 0,073). Ambas as estratégias apresentaram melhora no escore de QVFA durante o seguimento (p < 0,001), sem diferença entre os grupos. Embora sem repercussão clínica ou impacto no teste de avaliação intelectual, 25% dos pacientes do grupo PVAC apresentou sinais de embolização cerebral na RNM cerebral. Conclusões Ambas as estratégias para manutenção do ritmo sinusal promoveram melhora na qualidade de vida de pacientes idosos com FA sintomática, sem diferença estatística nos desfechos clínicos preconizados. Estudos adicionais usando tecnologias com melhor perfil de segurança são necessários para avaliar os benefícios da AC em pacientes idosos com FA.
Abstract Background There are no randomized studies comparing the maintenance of sinus rhythm after catheter ablation (CA) concerning treatment with antiarrhythmic drugs (AA) in elderly patients with paroxysmal atrial fibrillation (AF). Objectives To compare the clinical results of pulmonary vein (PV) isolation with the second-generation PVAC Gold catheter against AA treatment in elderly people with recurrent symptomatic paroxysmal AF, refractory to at least one AA, and without structural heart disease. Methods Sixty patients with paroxysmal AF ≥ 65 years old were randomized to two forms of treatment: group 1: CA and group 2: AA drugs. The primary outcome was the AF recurrence-free rate after at least one year of follow-up. Secondary outcomes were: progression to persistent forms of AF, impact on quality of life (QOLF), and complications. The significance level adopted in the statistical analysis was 5% (p<0.05). Results The AF recurrence-free rate was 80% (10% with amiodarone) in the CA group, after 1.3 procedures per patient and 65% in the AA group (60% with amiodarone), (p = 0.119) in an average follow-up of 719 days (Q1: 566; Q3: 730). The persistent AF free rate was 83.4% in the AC group and 67.7% in the AA group (p = 0.073) Both strategies showed an improvement in the AFQoL score during follow-up (p < 0.001), with no difference between the groups. Although without clinical repercussions or impact on the intellectual assessment test, 25% of patients in the CA group showed signs of cerebral embolization on brain MRI. Conclusions Both strategies for maintaining sinus rhythm promoted an improvement in the quality of life of elderly patients with symptomatic AF, with no statistical difference in the clinical outcomes. Additional studies using technologies with a better safety profile are needed to evaluate the benefits of CA in elderly patients with AF.

A diagnosis of congenital long QT interval syndrome based on history and electrocardiogram was made in a child in the absence of readily available genetic testing. A genotype 3 (LQT3) was suspected after exclusion of other variants as the child was non?responsive to beta?blocker and sodium channel blocker medication. As the child continues to show episodic bradycardia, polymorphic ventricular ectopy, and T?wave alternans, a single?chamber automated implantable cardioverter?defibrillator implantation was done successfully. This report highlights how the diagnosis of LQT3 was arrived at as well as the anesthetic challenges in the management of patients with LQTS.

Resumo Fundamento A ablação por cateter é uma terapia bem estabelecida para controle do ritmo cardíaco em pacientes refratários ou intolerantes a drogas antiarrítmicas (DAA). Porém, a eficácia desse procedimento comparada à de DAA como estratégia de primeira linha no controle do ritmo cardíaco na fibrilação atrial é menos conhecida. Objetivos Conduzir uma revisão sistemática e metanálise da ablação por cateter vs. DAA em pacientes sem nenhum tratamento prévio para controle do ritmo. Métodos Buscamos, nos bancos de dados do PubMed, EMBASE, e Cochrane, ensaios randomizados controlados que compararam ablação por cateter com DAA para controle do ritmo cardíaco em pacientes com FA sintomática e descreveram os seguintes desfechos: (1) recorrência de taquiarritmia atrial (TA); (2) FA sintomática; (3) internações hospitalares; e (4) bradicardia sintomática. A heterogeneidade foi avaliada por estatística I2. Valores de p menores que 0,05 foram considerados estatisticamente significativos. Resultados Incluímos cinco ensaios com 994 pacientes, dos quais 502 (50,5%) foram submetidos à ablação por cateter. O período médio de acompanhamento foi de um a cinco anos. Recorrências de TA (OR 0,36; IC95% 0,25-0,52; p<0,001) e de FA sintomática (OR 0,32; IC95% 0,18-0,57; p<0,001), e internações hospitalares (OR 0,25; IC95% 0,15-0,42; p<0,001) foram menos frequentes nos pacientes tratados com ablação por cateter que naqueles tratados com DAA. Bradicardia sintomática não foi diferente entre os grupos (OR 0,55; IC95% 0,18-1,65; p=0,28). Derrame ou tamponamento pericárdico significativo ocorreu em oito dos 464 (1,7%) pacientes no grupo submetido à ablação. Conclusão Esses achados sugerem maior eficácia da ablação por cateter que das DAA como estratégia inicial de controle do ritmo cardíaco em pacientes com DA sintomática.
Abstract Background Catheter ablation is a well-established therapy for rhythm control in patients who are refractory or intolerant to anti-arrhythmic drugs (AAD). Less is known about the efficacy of catheter ablation compared with AAD as a first-line strategy for rhythm control in atrial fibrillation (AF). Objectives We aimed to perform a systematic review and meta-analysis of catheter ablation vs. AAD in patients naïve to prior rhythm control therapies. Methods PubMed, EMBASE, and Cochrane databases were searched for randomized controlled trials that compared catheter ablation to AAD for initial rhythm control in symptomatic AF and reported the outcomes of (1) recurrent atrial tachyarrhythmias (ATs); (2) symptomatic AF; (3) hospitalizations; and (4) symptomatic bradycardia. Heterogeneity was examined with I2statistics. P values of < 0.05 were considered statistically significant. Results We included five trials with 994 patients, of whom 502 (50.5%) underwent catheter ablation. Mean follow-up ranged from one to five years. Recurrences of AT (OR 0.36; 95% CI 0.25-0.52; p<0.001) and symptomatic AF (OR 0.32; 95% CI 0.18-0.57; p<0.001), and hospitalizations (OR 0.25; 95% CI 0.15-0.42; p<0.001) were significantly less frequent in patients treated with catheter ablation compared with AAD. Symptomatic bradycardia was not significantly different between groups (OR 0.55; 95% CI 0.18-1.65; p=0.28). Significant pericardial effusions or tamponade occurred in eight of 464 (1.7%) patients in the catheter ablation group. Conclusion These findings suggest that catheter ablation has superior efficacy to AAD as an initial rhythm control strategy in patients with symptomatic AF.
RÉSUMÉ
Abstract New translational concepts on cellular and tissue substrate of cardiac arrhythmias have been responsible for the development of non-pharmacological interventions, with important achievements compared to the conventional approach with antiarrhythmic drugs. In addition, the increasing knowledge of anatomical and electrophysiological studies, sophisticated mapping methods, special catheters, and controlled clinical trials have favored the progression of ablation of tachyarrhythmias, particularly of ventricular tachyarrhythmias and atrial fibrillation.

Summary Atrial fibrillation alters the heart's hemodynamicfunction, being it a risk factor for thromboembolic accidents, complications and symptoms related with oneself cardiac arrhythmia. Restoring or preserving sinus rhythm is an important part of its management, for that two types of Restitution are established, one by an elec-tric shock and other by the use of drugs, both are valid, however there are important aspects to consider. The work objective is to compare the characteristics and indications for the use of electrical and pharmacological cardioversion in patients with atrial fibrillation. A comparison was made between both considering the characteristics of each method, techniques, mechanism, im-portant points to take into account, indications, complications and effectiveness. The right patient choice and a proper technique is significant to restore a normal heart rhythm. Both have specific characteristics and limitations. At the acting moment, there is no procedure that can be considered optimal, sometimes it is necessary to resort to a combined strategy. It has been noticed that the prescription of antiarrhythmic drugs before an electrical cardioversion can be useful to increase success and prevent it.

Abstract Background: D-limonene (DL) is a monoterpene and is the major component in the essential oil of citrus fruit. It presents antihyperglycemic and vasodilatation activities. Objectives: This study evaluated the cardiovascular effects and potential antiarrhythmic of DL in rats. Methods: Hemodynamic and electrocardiographic (ECG) parameters were measured in male Wistar rats, which under anesthesia had been cannulated in the abdominal aorta and lower vena cava and had electrodes subcutaneously implanted. In the in vitro approach, the heart was removed and perfused using the Langendorff technique. The significance level adopted was 5% (p < 0.05). Results: DL, in doses of 10, 20, and 40 mg/kg (i.v), produced intense and persistent bradycardia associated with hypotension. Bradycardia with prolonged QTc was observed in the ECG in vivo recording. In the in vivo model of arrhythmia induced by Bay K8644, DL (10 mg/kg) decreased the arrhythmia score from 15.33 ± 3.52 to 4.0 ± 2.64 u.a (p < 0.05, n = 4). In isolated perfused hearts, DL (10-3 M) promoted significant reductions in heart rate (from 228.6 ± 8.5 ms to 196.0 ± 9.3 bpm; p < 0.05) and left ventricular development pressure (from 25.2 ± 3.4 to 5.9 ± 1.8 mmHg; n = 5, p < 0.05). Conclusions: DL produces bradycardia and antiarrhythmic activity in rat heart.
Resumo Fundamento: O D-limoneno (DL) é um monoterpeno e o principal componente do óleo essencial de frutas cítricas. Ele apresenta atividades anti-hiperglicêmicas e vasodilatadoras. Objetivos: Este estudo avaliou os efeitos cardiovasculares e antiarrítmicos potenciais do DL em ratos. Métodos: Os parâmetros hemodinâmicos e eletrocardiográficos (ECG) foram mensurados em ratos Wistar machos que, sob anestesia, tiveram a aorta abdominal e a veia cava inferior canuladas e receberam eletrodos implantados subcutaneamente. Na abordagem in vitro, o coração foi removido e perfundido utilizando a técnica de Langendorff. O nível de significância adotado foi de 5% (p < 0,05). Resultados: DL, nas doses de 10, 20 e 40 mg/kg (i.v), produziu bradicardia intensa e persistente associada à hipotensão. A bradicardia com QTc prolongado foi observada no registro in vivo do ECG. No modelo in vivo de arritmia induzida por Bay K8644, DL (10 mg / kg) houve diminuição do escore da arritmia de 15,33 ± 3,52 para 4,0 ± 2,64 u.a (p < 0,05, n = 4). Em corações perfundidos isolados, o DL (10-3 M) promoveu reduções significativas na frequência cardíaca (de 228,6 ± 8,5 ms para 196,0 ± 9,3 bpm; p < 0,05) e na pressão desenvolvida do ventrículo esquerdo (de 25,2 ± 3,4 para 5,9 ± 1,8 mmHg; n = 5, p < 0,05). Conclusões: O DL produz bradicardia e atividade antiarrítmica no coração de ratos.

Objective: To investigate the current status of tachyarrhythmia treatment and outcomes in emergency patients. Methods: A total of 250 tachyarrhythmia patients treated in emergency departments from 1 tertiary hospital, 1 secondary hospital and 1 cardiovascular hospital in Beijing were enrolled. The baseline condition, type of tachyarrhythmia such as atrial fibrillation (AF)/atrial flutter, intravenous medication, prognosis and the choice of anticoagulation therapy were collected and statistically analyzed. Results: The mean age of patients was 64 years including 123/250 (49.2%) female. Common previous histories included 135 (54.0%) cases of hypertension, 93 (37.2%) cases of CAD, 29 (11.6%) cases of stroke/TIA, 29 (11.6%) cases of valvular heart disease and 18 (7.2%) cases of cardiomyopathy; 136 (54.4%) cases combined with organic heart disease. 123 (49.2) cases had previous atrial flutter/AF. The most common type of tachyarrhythmia was AF (172 cases, 68.8%) and the rest in turn, were supra-ventricular tachycardia (41 cases, 16.4%), ventricular tachycardia (23 cases, 9.2%), atrial flutter (21 cases, 8.4%), atrial tachycardia (12 cases, 4.6%) and premature ventricular contraction (5 cases, 2%). The most commonly used drug for treating supra-ventricular tachycardia was propafenone (151 cases, 60.4%), commonly used drug for treating supra-ventricular tachycardia and ventricular arrhythmia was amiodarone. With proper treatment, arrhythmia was stopped in 56% (140 cases), improved in 40% (100 cases) and unchanged or died in 10% (25 cases). 107 non-valvular AF/atrial flutter patients received low molecular heparin for anticoagulation therapy and only 25 patients continued oral anticoagulant therapy after discharge.Conclusion: In our research, most emergency patients were treated consistently with current guidelines. The choice of medication and anticoagulation therapy in AF patients should be improved.

Objective To study the efficacy and safety of ibutilide for AF and atrial flutter.Methods Thirty-two AF and atrial flutter patients with arrhythmia ≤3 months were randomly divided into ibutilide treatment group (n=17) and amiodarone treatment group (n=15).The patients in ibutilide treatment group were treated with 10 ml 5% glucose injection containing 1 mg ibutilide,which was repeated after 10 min if it was ineffective and those in amiodarone treatment group were treated with 10 ml 5% glucose injection containing 150 mg amiodarone,which was repeated after 10 min if it was ineffective.Results The total recovery rate of AF and atrial flutter was significantly higher in ibutilide treatment group than in amiodarone treatment group (64.7% vs 40.0%,P<0.05).The mean recovery time of AF and atrial flutter was significantly shorter in ibutilide treatment group than in amiodarone treatment group (29.28±12.57 min vs 70.59±16.83 min,P<0.01).Conclusion Ibutilide can rapidly recover AF and atrial flutter with a high success rate and a reliable safety.The therapeutic effect of ibutilide is better than that of amiodarone for AF and atrial flutter.
RÉSUMÉ
Rhythm control therapy is the main strategy for restoring and maintaining sinus rhythm in patients with non-valvular atrial fibrillation (NVAF). Sinus rhythm is better restored and maintained with antiarrhythmic drugs than with placebo treatment. In addition, catheter ablation or combination therapy is more effective than antiarrhythmic drugs for treating NVAF. However, in most clinical trials to date, rhythm control therapy has resulted in neutral clinical outcomes compared with rate control therapy. The decision to undergo rhythm control therapy should be based on age, atrial fibrillation (AF)-related symptoms, type of AF, structural heart disease, and underlying comorbidities. For now, rhythm control therapy is indicated to improve symptoms in patients with NVAF who have refractory symptoms after adequate rate control therapy. The Korean Heart Rhythm Society organized the Korean AF Management Guideline Committee and analyzed all available data, including South Korean patients with NVAF. This review article provides general principles and detailed methodology for rhythm control therapy in South Korean patients with NVAF.

Resumen Fundamento y objetivos: La fibrilación auricular es la arritmia mantenida más común. El estudio pretende conocer la prevalencia de fibrilación auricular en la población general, y evaluar las características y el manejo de los casos con fibrilación auricular no valvular. Métodos: Estudio transversal exploratorio en una muestra de la población de un Departamento de Salud (n = 30.024) de sujetos mayores de 18 años con diagnóstico electrocardiográfico de fibrilación auricular en la historia clínica electrónica de atención primaria. Se analizan características clínicas, manejo y tratamiento. Resultados: De un total de 629 pacientes con diagnóstico de fibrilación auricular, lo que representa una prevalencia del 2,1% (8,06% en > 65 años), fueron seleccionados para el estudio 505 casos con fibrilación auricular no valvular. La edad media fue 77,4 ± 10 años, 55% mujeres. Se objetivó cardiopatía estructural en el 32% de casos e insuficiencia cardiaca en el 29,5%. El 72% de pacientes recibía tratamiento anticoagulante, 60% con antivitamina K y 12% con anticoagulantes directos. Entre los primeros, solo el 53% mantenía un tiempo en rango terapéutico ≥ 65% según el método de Rosendaal. La forma de presentación persistente-permanente fue más frecuente (60,8%), seguida de la paroxística (39,2%). Conclusiones: La prevalencia de fibrilación auricular fue del 2,1%, aumentando con la edad, con elevada proporción de cardiopatía concomitante. La proporción de pacientes anticoagulados y la calidad de la anticoagulación son deficientes, revelándose así la necesidad de mejor monitorización y mayor utilización de nuevos anticoagulantes directos en los casos indicados.
Abstract Background and objectives: Atrial fibrillation is the most common type of constant arrhythmia. The study aims to know the prevalence of atrial fibrillation in the general population and to assess the features and management of non-valvular atrial fibrillation. Methods: Cross-sectional exploratory study of a population sample from a Health department (n=30.024) of individuals over 18 years with electrocardiographic diagnosis of atrial fibrillation in the primary care electronic medical records. Clinical features, management and treatments are analyzed. Results: Out of a total of 629 patients with an atrial fibrillation diagnosis, which represents a 2.1% prevalence (8.06% in >65 years), 505 cases with non-valvular atrial fibrillation were selected for the study. Average age was 77.4 ± 10 years, 55% female patients. Structural heart disease was detected in 32% of the cases, and cardiac failure in 29.5% of the cases. 72% of the patients were receiving anticoagulation therapy, 60% with antivitamin K drugs and 12% with direct anticoagulants. Among the former group, only 53% kept a time within the therapeutic range ≥65% according to the Rosendaal method. The most frequent presentation was persistentpermanent (60.8%), followed by paroxysmal (39.2%). Conclusions: Prevalence of atrial fibrillation was 2.1%, increasing with age, with a high proportion of accompanying heart disease. The proportion of anticoagulated patients and the quality of anticoagulation were poor, thus revealing the need for improved monitoring and wider use of new direct anticoagulants in the indicated cases.

Resumen Durante años las drogas antiarrítmicas (DAA) han constituido el tratamiento fundacional para los pacientes con fibrilación auricular paroxística (FAP) en los cuales se desea mantener el ritmo sinusal. Debido a las limitaciones en su eficacia, principalmente a largo plazo, sumado a la gran proporción de pacientes que discontinúan la terapia por efectos adversos, nuevas terapias no farmacológicas han sido desarrolladas con el fin de lograr un adecuado control del ritmo. En la última década la ablación por catéter se ha mostrado como la terapia más efectiva y posiblemente la más segura en aquellos pacientes con falla del tratamiento antiarrítmico. Estudios randomizados y metaanálisis recientemente publicados indican que la ablación podría ser considerada como primera línea de terapia en pacientes seleccionados con FAP en quienes se busca controlar el ritmo. Por lo tanto, en este artículo revisaremos la evidencia actual que avala el uso de DAA o ablación en la FAP.
