ABSTRACT

Adverse consequences of the coronavirus disease 2019 (COVID-19) vaccination which have been reported in scientific papers are varied. One possible but rare consequence is myocarditis, which may have a diversity of clinical manifestations. We report a case of a 70-year-old man who presented to the hospital for some syncope, 3 days after his first COVID-19 AstraZeneca Vaccination. Initial electrocardiogram (ECG) showed a long QT interval (QTc = 600 milliseconds). Laboratory tests revealed elevated troponin and lack of evidence of viral infection. Further investigations revealed the vaccine-induced myocarditis and arrhythmias linked to it. Within one week of magnesium treatment, the QT interval was completely corrected, and the patient discharged with no typical syncope attacks. This case like the previous reported one confirms that myocarditis is a complication of COVID-19 vaccine, but implies its clinical manifestations may be varied and even may happen after the single dose of vaccination.

ABSTRACT

AIM: To assess the changes induced by the COVID-19 lockdown on cardiac biometric variables recorded using an implantable cardiac monitor (ICM) in a patient population monitored for syncope work-up, as well to assess whether there has been an effect on arrhythmic events among the patients. METHODS: Longitudinal cohort study. We included 245 adult patients monitored with an ICM indicated for the investigation of syncope. The records from days 1 to 12 March 2020 (prior to the institution of lockdown by the state government) with days 16 to 28 March 2020 were compared. RESULTS: Daily physical exercise reduced markedly after the imposition of lockdown (132 [55-233] minutes vs. 78 [21-154] minutes). The mean daytime HR prior to lockdown was 77 [69-85] bpm, whereas during lockdown it was 74 [66-81] bpm. During the lockdown period, a drop in the variability in heart rate (114 [94-136] ms vs. 111 [92-133] ms) was observed. Although the incidence of AF was similar over both periods, the daily AF burden was significantly higher post-lockdown (405 [391-425] minutes vs. 423 [423-537] minutes). No differences in the number of other arrhythmias were found. CONCLUSIONS: The establishment of mandatory lockdown has led to a marked drop in daily physical activity in this population which probably explains changes observed in other cardiac biometric variables. Although, in the short term, we have not documented an increased risk of arrhythmia, we cannot rule out an effect in the medium to long term or in other populations of at-risk patients.

ABSTRACT

Összefoglaló. Egy 61 éves, SARS-CoV-2-fertozött, traumás syncopés nobeteg rosszullétének hátterében orthostaticus hypotonia igazolódott. A vírusfertozés megszunése után az orthostaticus hypotonia megszunt, de a posturalis tachycardia fennmaradt. A syncopénak egyéb okát kimutatni nem tudtuk. A SARS-CoV-2-fertozésnek egyéb tünete, illetve szervi manifesztációja nem volt. Tudomásunk szerint ez az elso eset, amelyben a SARS-CoV-2-infekció egyedüli tünete a syncope. Orv Hetil. 2021; 162(7): 243-245. Summary. Orthostatic hypotension was demonstrated in the background of malaise in a 61-year-old SARS-CoV-2 infected female traumatic syncope. After cessation of the virus infection, orthostatic hypotension resolved, but postural tachycardia persisted. No other cause of syncope could be detected. There were no other symptoms or organ manifestations of SARS-CoC-2 infection. To our knowledge, this is the first case where the only symptom of SARS-CoV-2 virus infection is syncope.
