The Current State of Refractory VF

The following guest post is written by MD candidate Joseph N. Ponce at McGovern Medical School, Houston TX, and describes the current state of evidence with adjunctive techniques to treat refractory VF.

Refractory ventricular fibrillation (RVF) is a life-threatening cardiac arrhythmia unresponsive to traditional methods of defibrillation and advanced cardiovascular life support (ACLS). Current literature lacks a uniform definition for RVF, however, some studies provide more specific clinical definitions of refractory ventricular fibrillation such as ventricular fibrillation that is resistant to at least three defibrillation attempts, 300 mg of amiodarone, and does not exhibit return of spontaneous circulation (ROSC) after > 10 min of cardiopulmonary resuscitation (CPR).… Read more
