Episode 190: Electrical Storm

VTAC storm, defined as three or more sustained episodes of ventricular fibrillation, ventricular tachycardia, or appropriate ICD shocks within 24 hours, represents a critical emergency requiring rapid intervention. Often driven by adrenergic surges or underlying cardiac pathology, management centers on immediate electrical cardioversion for hemodynamically unstable patients. While amiodarone serves as the primary antiarrhythmic, propranolol offers significant benefit for early arrhythmia cessation due to its non-selective beta-blockade. Sedation strategies require careful selection, as agents like ketamine may exacerbate cardiac irritability. Beyond pharmacotherapy, clinicians must address reversible causes, including electrolyte imbalances and ischemia, while engaging cardiology early for advanced interventions like stellate ganglion blocks or mechanical circulatory support. Senior resident Dr. Reed Colling highlights these essential clinical approaches to navigating this formidable cardiac pathology.
