Why the study?
Does reception of appropriate shocks from an implantable cardioverter defibrillator affect survival in patients with life-threatening ventricular tachyarrhythmias?
Does reception of appropriate shocks from an implantable cardioverter defibrillator affect survival in patients with life-threatening ventricular tachyarrhythmias?
Patients receiving appropriate ICD shocks have similar overall survival to those who do not, challenging previous reports of inordinately high mortality in this group.
Appropriate ICD shocks were not associated with worse overall survival; leaves open sudden death implications and challenges prior high-mortality reports.
