Spurious redetection of sinus rhythm by an implantable cardioverter defibrillator during spontaneous ventricular fibrillation.
Implantable cardioverter defibrillator undersensing leading to delayed or aborted therapy delivery has been reported with induced arrhythmias and following failed defibrillator shocks. We describe a case in which spurious redetection of sinus rhythm during a spontaneous episode of ventricular fibrillation resulted in aborted device therapy.
