Lead dislodgement complicated with paroxysmal atrial fibrillation as a rare cause of inappropriate implantable cardioverter defibrillator shock:a case report

摘要

Inappropriate shock of implantable cardioverter defibrillator(ICD)is a rare but catastrophic phenomenon.Inappropriate shock is usually caused by oversensing of noise or supraventricular tachycardias(SVTs).However,inappropriate shock can also be triggered by other uncommon mechanisms.Lead dislodgement is also rare in patients with cardiac implantable electronic devices,which can manifest as pacing failure and mis-sensing of other signals.
