What does this research mean for the field?

Electrical storm in ICD patients is best defined as three appropriate ventricular tachyarrhythmia detections in 24 hours, and its optimal management requires reducing sympathetic tone through beta-blockers, benzodiazepines, and shock-avoiding ICD programming. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Implication

Electrical storm's hospitalization burden in ICD patients warrants attention; leaves open optimal prevention strategies.

Key Points

To define electrical storm in patients with implantable cardioverter defibrillators and characterize its clinical incidence, triggers, prognosis, and therapeutic management.
Narrative review synthesizing diagnostic criteria, epidemiological data, and pathophysiological mechanisms of electrical storm.
Evaluation of pharmacologic, interventional catheter ablation, and device programming strategies for acute management and prevention.
Electrical storm is defined as 3 or more appropriate ventricular tachycardia detections within 24 hours, occurring in approximately 25% of defibrillator patients over 3 years.
Identifiable triggers are present in approximately 66% of cases, presenting a 1% immediate mortality rate but high hospitalization rates of 50% to 80%.
Effective therapy centers on reducing elevated sympathetic tone with beta-blockers and benzodiazepines, alongside intravenous amiodarone, catheter ablation, and shock-minimizing device programming.
