Repetitive ICD discharges due to diaphragmatic electromyopotential oversensing can serve as an early sign of right ventricular lead perforation.
May prompt evaluation for RV lead perforation after unexplained repetitive ICD shocks; leaves open prospective validation of this sign.
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.
