More than 350,000 cardiac arrests occur each year in North America. Approximately 100,000 of these arrests are due to shockable rhythms. Unfortunately, many patients have refractory ventricular fibrillation and do not respond to many attempts at standard defibrillation. In this podcast, we discuss a recent study that evaluated double sequential external defibrillation and vector-change defibrillation compared to standard defibrillation in patients with refractory ventricular fibrillation in OHCA.
