Double Sequential External Defibrillation: A New Frontier in the Treatment of Refractory Ventricular Fibrillation?

Refractory ventricular fibrillation (VF) remains one of the most formidable challenges in cardiopulmonary resuscitation. Despite significant advances in the management of out-of-hospital cardiac arrests, some patients do not respond to standard defibrillation techniques, seriously compromising their chances of survival. In this context, new defibrillation approaches have emerged in recent years, particularly double sequential external defibrillation […]
