Accelerated ventricular rhythm in childhood.

Four patients, aged 6 to 14 years, with accelerated ventricular rhythm were studied from June 1976 to June 1978. Three were asymptomatic and had no evidence of cardiac disease. One patient had equivocal evidence of myocarditis. All four patients are well without therapy. The benign nature of this rhythm and the importance of its differentiation from ventricular tachycardia is stressed.
