Abstract

Defibrillation testing (DT) has been an integral component of implantable cardioverter-defibrillator (ICD) implantation procedure for over the last 20 years. The induction of ventricular fibrillation (VF) during the DT is the accepted method to determine a sufficient safety margin between the maximum shock energy of the ICD and the shock energy required for defibrillation life threatening ventricular arrhythmias. Nowadays, ICD technology has evolved and the likelihood of successful VF defibrillation achieved 90%, which determines a trend toward ICD implantation without DT. The topic of this article are questions and answers concerning the problems with elevated defibrillation threshold and the appropriateness and safety of routine intraoperative DT.
