  1. Mean ± S.D.; CPR, cardiopulmonary resuscitation; ECG, electrocardiogram; PEA, pulseless electrical activity; VF, ventricular fibrillation; VT, ventricular tachycardia; ROSC, return of spontaneous circulation; GOS, Glasgow outcome scale
  2. Gender, witnessed arrest, bystander CPR, initial ECG on admission and cause of arrest in both groups were analysed by Chi-squared test or Fisher's exact test.
  3. Age, resuscitation duration and time between MRI and ROSC in both groups were compared by t-test.
