Stellate ganglion local anesthetic blockade and neurolysis for the treatment of refractory ventricular fibrillation.

Electrical storm (ES) is a syndrome characterized by recurrent ventricular fibrillation or tachycardia. It is a major clinical challenge and is often unresponsive to conventional drug therapy; instead, its treatment requires multiple attempts at electrical defibrillation. Sympathetic hyperactivity is an important modulator of ventricular arrhythmias, including ES. We report a case of ES treated safely and effectively with pharmacologic sympathectomy involving diagnostic continuous stellate ganglion blockade with local anesthetic followed by therapeutic neurolysis. This technique reduced ES in a patient for whom conservative medical and interventional procedures were ineffective.
