Okubo M, et al. – This study strived to examine the trend in outcome from ventricular fibrillation/pulseless ventricular tachycardia (VF/pVT) out–of–hospital cardiac arrest (OHCA) in Rochester MN. A significant improving secular trend was observed in neurologically intact survival from VF/pVT cardiac arrests with a relatively high recent survival rate in this Emergency Medical Services (EMS) System.
