[Successful treatment of ventricular tachycardia by transvenous electrical ablation of the right Tawara branch].

Recurrent episodes of ventricular tachycardia not responding to medical treatment occurred in a 56 year old man. Electrophysiological investigation showed ventricular tachycardia due to bundle branch reentry. Using a method similar to catheter ablation of the atrioventricular junction an ablation of the right bundle branch was performed by an electrical shock of 250 J. While before the ablation ventricular tachycardia occurred several times a day, and its induction by programmed ventricular stimulation was facilitated by the administration of antiarrhythmic drugs, no initiation of ventricular tachycardia was possible after ablation of the right bundle branch. Over a follow-up of 4 weeks the patient has not suffered from tachycardia and the artificial right bundle branch block persists.
