External electric countershock is an effective method for terminating drug-refractory supraventricular arrhythmias in patients with congenital heart disease.

May support countershock in refractory SVT with congenital heart disease; hypothesis-generating and leaves open controlled validation.
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.
