Controversy exists regarding the incidence, electrogenesis, clinical manifestations, management, and prognosis of idioventricular rhythm in acute myocardial infarction, a mechanism originally described by us. This report documents our recent experience with idioventricular rhythm and attempts to resolve this dilemma. Idioventricular rhythm occurred in 68 of 300 consecutive patients with acute myocardial infarction monitored by a relay telemetric system. Unlike paroxysmal ventricular tachycardia, idioventricular rhythm had a gradual onset and a rate that rarely exceeded 100/ min. It usually arose as a ventricular escape mechanism in the setting of sinus bradycardia or marked sinus arrhythmia. Idioventricular rhythm was seen more commonly
