Official Title: Effect of Right Ventricular Lead Position on Defibrillation Threshold
Brief Summary: The purpose of this study is to determine how the position of the right ventricular (RV) coil of an implantable cardioverter defibrillator (apex versus septum) affects the defibrillation threshold; specifically, can defibrillator threshold be improved by implantation site selection.
