Electric storm is defined as three or more episodes of ventricular tachyarrhythmias within 24 hours that require interruption. It’s incidence
in patients with implanted cardioverter-defibrillator ranges between 10–20 % per one year. Electric storm occurs suddenly and mostly
without indentifiable precipitating factor. The therapeutic approach is complex. From pharmacotherapy, sedation and combination of
betablockers and amiodarone is recommended. In case of recurrent arrhythmias despite this treatment, catheter ablation and modification
of arrhythmogenic substrate is indicated. If the electric storm is caused by polymorphic ventricular tachycardias, it is possible in
selected patients to perform ablation of the triggering ectopy. Electric storm is severe, life-threatening situation that adversely impacts
prognosis. Catheter ablation should be in these patients indicated early and may become life-saving therapy.
