Resuscitation Protocol. VF was untreated for 8 minutes in all acute MI swine. Following this period swine underwent either a defibrillation shock (up to 3 stacked shocks, shock first group) or chest compressions for 3 minutes prior to the first defibrillation shock (pre-shock CPR group). Epinephrine was administered if resuscitation continued beyond 20 minutes. If ROSC was achieved, the animal was monitored for 1 hour, followed by observation in a holding pen for 24 hours, after which time the neurological assessment was performed (see text).
