Key result
COVID-19 infection can atypically present as fatal high-grade atrioventricular nodal block and conduction abnormalities in a young adult with normal coronary arteries.
Case Report (n=1)
COVID-19 can atypically present with fatal bradyarrhythmias and conduction abnormalities such as high-grade AV block.
Rare fatal AV block may occur in young COVID-19 patients; hypothesis-generating for myocarditis-related conduction disease.
While respiratory system disease, including pneumonia, remains the principal clinical presentation, several cardiovascular complications of coronavirus disease 2019 (COVID-19) including myocardial infarction, myocarditis, and tachyarrhythmias were reported. We present an unusual case of fatal high-grade atrioventricular nodal block in a young adult male with COVID-19 infection in the occurrence of normal coronary arteries. Marked inflammatory response and myocarditis are the most likely contributing factors to electrical conduction system disturbance. It is appropriate for the clinicians to be aware of the fact that COVID-19 can atypically present as bradyarrhythmia and conduction abnormalities.

Tabatabai et al. (2021) conducted a case report in COVID-19 infection with high-grade atrioventricular nodal block (n=1). COVID-19 infection was evaluated on High-grade atrioventricular nodal block. COVID-19 infection can atypically present as fatal high-grade atrioventricular nodal block and conduction abnormalities in a young adult with normal coronary arteries.
