Abstract
Coronavirus disease (COVID-19) has infected millions of people worldwide. Its cardiac presentations include myocarditis, arrhythmias and structural heart changes even in young and healthy individuals. The long-term sequelae of these manifestations are unknown. We describe a unique combination of complete heart block and atrial flutter in the setting of COVID-19. SARS-CoV-2 virulence mechanisms can cause fibrosis in the myocardium resulting in loss of sinus node dominance. The paradoxical finding of atrial flutter and complete heart block is very rare. Prompt cardiac evaluation and electrophysiological testing are important. Cardiac magnetic resonance imaging (cMRI) and endomyocardial biopsies are the gold standard investigations. Anticoagulation should be administered until atrioventricular synchrony is achieved.
Learning points: Simultaneous atrial flutter and third-degree atrioventricular block (AVB) caused by COVID-19 infection should be treated with a pacemaker according to heart block guidelines.During the COVID-19 pandemic, we recommend leadless pacemaker implantation for third-degree AVB as it has a lower risk of infection compared with traditional percutaneous procedures.Due to a lack of long-term data, patients with cardiac manifestations from COVID-19 require close follow-up with individualized surveillance schedules.
