| Popis: | An 81-year-old man was scheduled for an elective implantable cardioverter defibrillator (ICD) generator exchange because of battery depletion. The Atlas™+ DR ICD (St. Jude Medical, Sylmar, CA) had been implanted in February 2007 for primary prevention. The ICD lead (Riata 1570, St. Jude Medical, Sylmar, CA) had been positioned via the left cephalic vein at the right ventricular apex. Prior to the ICD generator exchange, which took place 70 months after the initial implantation, all routine device interrogations revealed normal electrical lead parameters, and cine-fluoroscopy of the lead showed normal appearance without any apparent fracture. We attempted to conduct high-voltage shock testing, as there was concern about the possibility of silent lead malfunction. Following delivery of the first high-voltage shock, the device declared “possibility of output circuit damage.” Subsequent shocks could not be delivered. Nonetheless, other lead parameters remained stable, and high-voltage lead impedance was |
