title: Multiple hardware complications in a patient with an ICD.
abstract: Hardware-related complications in implantable cardioverter/defibrillators (ICD) are still a common problem. Identifying underlying reasons becomes more and more difficult as the complexity of ICD systems increases. We report a patient with a dual chamber ICD (DDD-ICD) who suffered multiple complications. These included: ventricular oversensing causing inappropriate shocks and episodes of asystole; an insulation defect resulting in ineffective shocks as a consequence of a short circuit between the active can device and a defective high voltage cable; and device dysfunction requiring several hospitalizations and operative system revisions.
