Pediatric defibrillation doses often fail to terminate prolonged out-of-hospital ventricular fibrillation in children

Termination of VF after a pediatric defibrillation dose is substantially worse for prolonged pediatric out-of-hospital VF cardiac arrest compared with in-hospital (short duration) ventricular fibrillation. The optimal pediatric defibrillation dose for prolonged VF is not known.
