A Case of Transient Complete Atrioventricular Block in Acute Viral Myocarditis

Arrythmias are often present and may lead to unexpected death in acute myocarditis. Occasionally, conduction disturbances are seen with varying degree of heart block yet complete atriove ntricular block is rare. We experienced a case of transient complete heart block caused by coxsackie B5myocarditis in a previously healthy 12-year-old girl. During the use of a transvenous temporary pacemaker for 5 days, the abnormal cardiac rhythm changed to sinus rhythm and clinical status improved progressively.
