Electrical storm (ES), arbitrarily defined as the occurrence of three or more separate episodes of ventricular tachycardia or fibrillation within a 24 h period, remains a difficult clinical entity to manage. The occurrence of multiple episodes in a short time frame has been described in a wide variety of clinical situations, ranging from the early post-myocardial infarction setting to the critically ill post-operative patient (e.g. electrolyte disturbance) to the patient who has an overdose of tricyclic antidepressants.
