title: Insulation failure with externalized conductor of a Linox SD lead: a case report.
abstract: A 53-year-old man with a dual-chamber implantable cardioverter-defibrillator presented to the electrophysiology (EP) lab for an EP study in evaluation of supraventricular tachycardia despite medical therapy. Fluoroscopic imaging during placement of diagnostic catheters demonstrated insulation failure with an externalized conductor on the right ventricular defibrillator lead just distal to the proximal defibrillator coil. Device interrogation revealed normal pacing, and shock impedances, normal sensing, and stable pacing thresholds.
