An electrical storm (ES) is a ventricular arrhythmia (VA) defined as the occurrence of three or more ventricular tachycardias (VT) in a day, separated by five-minute intervals, or the existence of unending VT despite antiarrhythmic drug therapy optimization. The goal of this chapter is to provide an overview of electrical storms in ICD therapy patients. During follow-up, 84 of 1274 patients with an implanted cardioverter-defibrillator (ICD) developed ES, according to the findings. During the first 134 days after ICD implantation, the incidence of ES in individuals with ICD can reach 20%. Because ES can be induced by a variety of factors, the pathophysiological process is unknown. VT and ventricular fibrillation (VF), global acute ischemia, and myocardial dysfunction are just a few of the clinical circumstances and mechanisms that cause myocardial dysfunction. Shocking cardiac death is three times more likely in patients with ES (SCD). Emergency sedation, ventilation, neuraxial modulation, pharmacological therapy (beta-blockers, amiodarone, sotalol, class I anti-arrhythmic medications), and catheter ablation are among the treatment options (CA). CA is a process for rescuing people. When pharmacological therapy has had little or no effect, this procedure is used. This method involves mapping the region first, then choosing between approaches (endocardial or epicardial) and several CA methods, which include radiofrequency ablation, irrigated radiofrequency ablation, pulsed radiofrequency ablation, alcohol ablation, and cryoablation.
