Electrical Storm: Current Evidence, Clinical Implications, and Future Perspectives

Purpose of Review Electrical storm (ES) is a life-threatening medical emergency of repetitive episodes of sustained ventricular arrhythmias within a short period. Its occurrence is associated with poor short- and long-term survival, even in patients with implantable cardioverter defibrillators (ICD). Management of ES is challenging and mainly based on retrospective studies. This article reviews the existing literature on ES, presents the available data regarding its management, and proposes a new algorithm based on current evidence.
