Arrhythmia occurring as the sole presenting feature in Covid-19.

Severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) infection is observed to be associated with several cardiac complications. Cardiac arrhythmias are frequently observed in critically ill patients and are usually associated with myocarditis. We report two patients with Covid-19, in whom serious arrhythmias were the sole presenting feature, in the absence of any of the known manifestations of the disease. Further research is required into this yet unknown mechanism of the effect of Covid-19 on the conduction system. Thus, managing patients with acute-onset arrhythmias of unexplained aetiology, even when they present without known clinical features of Covid-19, should be done with care.
