An overview of the management of electrical storm.

Electrical storm is defined as recurrent, hemodynamically destabilizing ventricular tachycardia or ventricular fibrillation occurring two or more times in a 24 h period, and usually requiring electrical cardioversion or defibrillation. Recent advances in the understanding of the pathogenesis of this serious arrhythmia and in its pharmacological management have improved the prognosis for patients experiencing electrical storm. In this article, several different clinical syndromes of electrical storm and the management of each are examined.
