Post-Myocardial Revascularization: As a Nidus for an Electrical Storm!

Electrical storm (ES) is a critical and potentially life-threatening cardiac rhythm disorder. It is characterized by the presence of three or more distinct episodes of sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) that necessitate appropriate termination. ES may occur in the setting of acute myocardial infarction or following myocardial reperfusion. An urgent treatment approach is necessary for better outcomes. We represent a case of a 64-year-old patient who presented with sudden chest pain and an episode of palpitations related to non-ST elevation myocardial infarction (NSTEMI), who has undergone percutaneous coronary intervention of the stenotic epicardial artery, but subsequently experienced an ES in the absence of stent thrombosis. ES presented in the form of sustained monomorphic VT that required synchronous direct current cardioversion, anti-arrhythmic drugs, deep sedation, and endotracheal intubation with a favorable course, with the patient being discharged after 14 days hospital stay. The practitioner should be mindful of the potential occurrence of ES following myocardial revascularization and should tailor the management approach.
