Congenital junctional ectopic tachycardia is an uncommon and potentially fatal arrhythmia that does not usually respond to medical therapy. We report a two month old infant with severe ventricular failure. The diagnosis was confirmed by electrophysiologic study. She underwent endocardial cryoablation of the His bundle during extracorporeal circulation and a ventricle epicardial-lead pacemaker was implanted. Eight years later the patient is still symptom-free without needing medical treatment.
