Cardiac manifestations are also being increasingly reported such as pericardial disease, myocardial injury and dysfunction, arrhythmias and conduction abnormalities. A 70-year-old male with asymptomatic COVID-19 infection developed a transient episode of complete heart block just prior to his planned discharge from hospital. There are only few case reports purporting the development of a transient complete heart block in patients with moderate to severe COVID-19 infection. However, to date, this is the first report of incidentally detected, asymptomatic COVID-19 infection manifesting as third degree heart block. http://pubs.sciepub.com/ajmcr/9/4/13/ajmcr-9-4-13.pdf Coronavirus complete heart block arrhythmia COVID-19 myocardial injury
