Aims: The novel coronavirus SARS-CoV-2 has shown the potential to significantly affect the cardiovascular system. Cardiac arrhythmias are commonly reported complications in COVID-19 hospitalized patients.
Methods and results: While tachyarrhythmias seem most common, we describe four cases of COVID-19 patients who developed a transient high-degree atrioventricular (AV) block during the course of their hospitalization. All four patients who developed a high-degree AV block during their hospitalization with COVID-19 did not require permanent pacing.
Conclusion: Similarly to most AV blocks associated with infectious organisms and given its transient nature, this case series suggests that conservative management strategies should be preferred in COVID-19 patients who develop complete heart block.
