Timing diagram of resuscitation protocol. Part A: G2000 Group: a 40 s pause starting 20 s before and ending 20 s after attempted defibrillation. Group A1: a 20 s pause just before attempted defibrillation. Group A2: a 20 s pause ending 30 s before attempted defibrillation. Group A3: a 10 s pause ending 30 s before attempted defibrillation. Part B: Group B: no pauses other than the 3 s pause at the defibrillation attempt. Once CPR was resumed after the first defibrillation attempt, the resuscitation protocol was identical for all 5 groups and included a pause for 3 s every 90 s to determine rhythm and perfusion and deliver a defibrillation shock if necessary.
