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