Ventricular Arrhythmias adjudication process:
Adjudicated VA were classified in one of the groups:
  1. VT if detected in any VT zone, according to individualized programming, lasting more than 4 beats;
  2. VF if detected in the VF zone according to individualized programming;
  3. VA requiring ATP, if any ATP was delivered during the episode of VT or VF;
  4. VA requiring shock therapy, if any shock was delivered during the episode of VT or VF.
Episodes were excluded if they were categorized after revision as supraventricular tachycardia or if they were thought to be secondary to device misinterpretation or malfunctioning.
