Inappropriate shock from nonphysiologic noise during implantation of a Boston Scientific COGNIS N119 biventricular implantable cardioverter-defibrillator (CRT-D).

摘要

Noise, often visible on the intracardiac electrogram (EGM), may affect sensing and result in inappropriate therapy in implanted cardiac rhythm management devices. We present a case of inappropriate shock from an uncommon cause of nbnphysiologic noise during implantation of a Boston Scientific COGNIS N119 cardiac resynchronization therapy defibrillator (CRT-D)
