Key result
Amiodarone controls repetitive SVT in all 3 patients.
Why the study?
Repetitive supraventricular tachycardia is an uncommon arrhythmia usually resistant to conventional antiarrhythmic drugs and often occurs in patients without structural heart disease.

Case series reveals effective arrhythmia control with amiodarone and ventricular pacing in patients with repetitive supraventricular tachycardia, suggesting a viable therapeutic approach.
Repetitive supraventricular tachycardia is an uncommon arrhythmia which usually occurs in patients free of structural heart disease. It is characterized by incessant short salvos of supraventricular tachycardia separated by only one or two normal sinus beats. Therapy with conventional antiarrhythmic drugs is usually ineffective. This report describes three patients with repetitive supraventricular tachycardia in whom evidence for associated sinus node dysfunction was observed. Amiodarone therapy, with ventricular pacing in two patients, has provided effective control of this arrhythmia in all three patients.

Haines et al. (1986) conducted a case report in Repetitive supraventricular tachycardia (n=3). Amiodarone (with ventricular pacing in two patients) was evaluated on Control of arrhythmia. Amiodarone therapy, combined with ventricular pacing in two cases, provided effective control of repetitive supraventricular tachycardia in all three patients.
