Tachyarrhythmias have been reported but the prevalence of bradyarrhythmia is unclear. Cases have been described of transient high\u2010degree atrioventricular (AV) block in COVID\u201019 that were managed conservatively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A database of all patients requiring temporary or permanent pacing in two linked cardiac centers was used to compare the number of procedures required during the first year of the pandemic compared to the corresponding period a year earlier. The database was cross\u2010referenced with a database of all patients testing positive for Sars\u2010Cov\u20102 infection in both institutions to identify patients who required temporary or permanent pacing during COVID\u201019.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The number of novel pacemaker implants was lower during the COVID\u201019 pandemic than the same period the previous year (540\u00a0vs. 629, respectively), with a similar proportion of high\u2010degree AV block (38.3%\u00a0vs. 33.2%, respectively, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.069). Four patients with the Sars\u2010Cov\u20102 infection had a pacemaker implanted for high\u2010degree AV block, two for sinus node dysfunction. Of this cohort of six patients, two succumbed to the COVID\u201019 illness and one from non\u2010COVID sepsis. Device interrogation demonstrated a sustained pacing requirement in all cases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>High\u2010degree AV block remained unaltered in prevalence during the COVID\u201019 pandemic. There was no evidence of transient high\u2010degree AV block in patients with the Sars\u2010Cov\u20102 infection. Our experience suggests that all clinically significant bradyarrhythmia should be treated by pacing according to usual protocols regardless of the COVID
