Figure 1 Frequency distribution pie chart for adjudicated mechanisms of SD of 68 consecutive patients with a non-thoracotomy implantable cardioverter defibrillator (ICD) during pre-clinical device evaluation. The portion labeled VT/VF-OTHER includes one each of conversion of supraventricular tachyarrhythmia to ventricular fibrillation (VF), untreated ventricular tachycardia (VT) (as programmed), failure to redetect VT/VF after a shock therapy and trauma from a motor vehicle accident secondary to treated VT/VF. EMD = electromechanical dissociation.
