Abstract

PURPOSE OF REVIEW:

With increasing use of implantable cardioverter defibrillators, physicians are increasingly called upon to manage recurrent ventricular tachycardia, sometimes in the form of frequent recurrences known as electrical storm (or ventricular tachycardia storm).

RECENT FINDINGS:

Standard antiarrhythmic drug therapy may suppress storms, but, when refractory, interventions such as catheter ablation or in some cases surgical cardiac denervation may be helpful. Earlier interventional management may confer better outcomes than persisting with antiarrhythmic pharmacologic therapy.

SUMMARY:

The clinical syndrome of electrical storm has been defined empirically. An outcome-derived definition may better guide clinicians on when and how to treat this emergent problem. When available, an early interventional approach is preferred.
