ICD programming schema for the three device manufacturers involved in the trial. A number followed by “J” indicates a shock therapy with the number referring to the shock energy in joules (J). ATP indicates anti‐tachycardia pacing; bpm, beats per minute; ICD, implantable cardioverter‐defibrillator; VF, ventricular fibrillation; VT, ventricular tachycardia.
