External Electrical Termination of Supraventricular Arrhythmias in Congenital Heart Disease

Abstract

Persistent supraventricular arrhythmias of the flutter or fibrillation-flutter type have been terminated by elective external electric countershock in three patients after drug therapy had been unsuccessful. It is suggested that this technic is a relatively safe and effective treatment for supraventricular as well as ventricular arrhythmias when anti-arrhythmic drugs have proved ineffective.
