Bradyarrhythmia in COVID-19 Patients

The emergence of coronavirus disease 2019 (COVID-19) in 2019 has rapidly become a global health emergency. COVID-19 develops from a severe acute respiratory syndrome coronavirus (SARS-CoV) infection, which directly impacts the cardiovascular system by disrupting angiotensin-converting enzyme-2 receptors in the tissues. This leads to severe complications that cause major morbidity and mortality. Several cardiovascular complications have been reported during the pandemic, including myocardial infarction, stroke, pulmonary embolism, myocarditis, and tachyarrhythmias. Although bradyarrhythmia is another cardiac event associated with COVID-19, it has been reported in only a few cases in the medical literature. Here, we report two cases of young adult patients who were admitted because of a positive reverse transcriptase-polymerase chain reaction test of SARS-CoV-2 and presented with bradycardia detected on electrocardiogram but had an otherwise normal health condition with no history of cardiovascular illness.
