Electrical Storm

Electrical storm, defined as recurrent stable ventricular tachycardia, requires a systematic five-pronged management approach: electricity, sympatholysis, antiarrhythmics, electrolyte optimization, and rescue strategies. Synchronized cardioversion serves as the primary electrical intervention, while aggressive sympatholysis—using agents like fentanyl and dexmedetomidine—is critical to mitigate endogenous catecholamine surges. First-line pharmacotherapy typically involves amiodarone, followed by lidocaine and beta-blockers, while avoiding pro-arrhythmic inotropes. Electrolyte correction, specifically targeting potassium levels above 4.4 mEq/L and magnesium above 2.2 mEq/L, remains essential for preventing recurrence. When standard measures fail, mechanical circulatory support, such as Impella or VA-ECMO, provides necessary hemodynamic stability. Clinicians must also address underlying triggers like heart failure or ischemia and exercise caution with pacemakers and LVADs, ensuring that device settings do not inadvertently facilitate pro-arrhythmic states or suction events.
