Inadequate ICD discharges due to diaphragmatic electromyopotential oversensing as the first sign of right ventricular lead perforation.

Right ventricular lead perforation, when acute, is a rare but potentially life-threatening complication of implantable cardioverter defibrillator (ICD) therapy. We report about a patient with early lead perforation presenting with repetitive ICD discharges due to oversensing of diaphragmatic electromyopotentials and describe the management of this complication.
