Background Despite advances in defibrillation technology, shock-refractory ventricular
fibrillation remains common during out-of-hospital cardiac arrest. Double sequential external …

Background. Ventricular fibrillation (VF) is considered the out-of-hospital cardiac arrest
(OOHCA) rhythm with the highest likelihood of neurologically intact survival. Unfortunately …

Objectives The primary objective was to determine the feasibility and safety of a cluster
randomized controlled trial (RCT) with crossover comparing vector change defibrillation …

Introduction Survival from out of hospital cardiac arrest (OHCA) is highest in victims with
shockable rhythms when early CPR and rapid defibrillation are provided. However, a subset …

Cardiac arrest is defined as the termination of cardiac activity associated with loss of
consciousness, of spontaneous breathing, and of circulation. Sudden cardiac arrest and …

Background—The most recent resuscitation guidelines have sought to improve the interface
between defibrillation and cardiopulmonary resuscitation; the survival impact of these …

STUDY OBJECTIVE: We sought to determine whether the delays in chest compressions and
defibrillation associated with an automated external defibrillator would adversely affect …

Context Defibrillation as soon as possible is standard treatment for patients with ventricular
fibrillation. A nonrandomized study indicates that after a few minutes of ventricular fibrillation …

Background: Survival from ventricular tachycardia (VT) or ventricular fibrillation (VF) arrest is
inversely related to delay to defibrillation. The automated external defibrillator (AED) has …

Background—Although biphasic, as compared with monophasic, waveform defibrillation for
cardiac arrest is increasing in use and popularity, whether it is truly a more lifesaving …
