title: [Radiofrequency catheter ablation of supraventricular tachycardia in an adult with corrected tetralogy of Fallot].
abstract: An 18 year old female with Fallot's tetralogy had undergone complete repair at thirteen years of age. Two years later she first presented a wide complex right bundle branch block tachycardia at a rate of 220 beats/min which could not be controlled on intravenous verapamil. Electrical shock successfully converted tachycardia to sinus rhythm, which showed typical Wolff-Parkinson-White syndrome. On electrophysiological study, the ortodromic tachycardia was found to be due to left lateral atrioventricular accessory pathway, which was ablated by radiofrequency catheter ablation. One year later she was symptom-free without antiarrhythmic medication.
