Electrical storm, also referred to as arrhythmic storm, refers to multiple recurrences of ventricular arrhythmias over a short period of time.

In most instances, the arrhythmia is ventricular tachycardia (VT), but polymorphic VT and ventricular fibrillation (VF) can also result in electrical storm.

The arrhythmias can be self-terminating but frequently are terminated using antiarrhythmic drugs or device-related therapies (defibrillation or anti-tachycardia pacing).

In contrast to repetitive ventricular arrhythmias occurring in electrical storm, incessant VT is defined as hemodynamically stable VT which persists for longer than one hour.
