This article describes the implantation of an automatic implantable cardioverter/defibrillator in a 69-year-old man with coronary artery disease and recurrent sustained ventricular tachycardia without the need for a thoracotomy/sternotomy and epicardial electrodes. The patient underwent serial electrophysiological evaluation that revealed drug-refractory ventricular tachycardia. Surgical ablation was considered and rejected due to advanced, severe, pulmonary disease. A triple electrode system using two transvenous catheter electrodes and a submuscular patch electrode in the left midaxillary line was employed. A single shock was delivered simultaneously over two spatially distinct current pathways and reproducibly defibrillated ventricular fibrillation with energies less than or equal to 10 J. The automatic implantable cardioverter/defibrillator was implanted in the anterior abdominal wall and demonstrated reproducible termination of ventricular tachycardia and ventricular fibrillation.
