Atypical Reasons for CRT Non-Response in a Pacing Induced Cardiomyopathy Patient

Pacing induced cardiomyopathy is a known complication of high percent right ventricular pacing. When treated with cardiac resynchronization therapy (CRT), most patients experience recovery of Left Ventricular (LV) systolic function. A small percentage of patients do not respond due to a number of factors. This case study exams a 30-year-old patient with pacemaker induced cardiomyopathy who was found to be a CRT non responder despite optimal left ventricular lead position and whose LVEF normalized following right ventricular lead revision.
