Ventricular fibrillation (VF) is a life-threatening cardiac arrhythmia that can lead to loss of cardiac function and sudden cardiac death. The most common cause of VF is ischemic cardiomyopathy, especially in the context of an acute coronary event. Prompt treatment with resuscitation and defibrillation can be lifesaving. Refractory VF, or pulseless ventricular tachycardia (pVT), refers to cases that do not respond to traditional advanced cardiac life-support (ACLS) measures, and it has a low survival rate. Some new life-saving interventions and novel techniques have been proposed as viable treatment options for patients presenting with refractory VF/pVT out-of-hospital cardiac arrest; these include extracorporeal membrane oxygenation (ECMO), esmolol, stellate ganglion block (SGB), and double sequential defibrillation (DSD). Recently, DSD has been discussed and used more frequently, but its survival rate is still not promising. We report a case of refractory VF caused by acute myocardial infarction that was treated with ACLS, DSD, ECMO, and cardiac catheterization in sequence, with a successful outcome.
