Resetting of Cardiac Ventricular Tachycardia Storm with Intravenous Potassium Chloride: A Case Report

Ventricular Tachycardia Storm (VTS) with hemodynamic instability is a life-threatening arrhythmia more often presents in patients with structural heart disease. Lack of response to cardioversion and/or antiarrhythmic drugs will have fatal consequences. We report a case of a hemodynamically unstable patient with Ventricular Tachycardia Storm refractory to intravenous antiarrhythmic medications, which finally responded to a slow bolus of IV potassium chloride. This case emphasizes the importance of identifying an electrolyte imbalance as a possible cause of a Ventricular Tachycardia storm and its rapid correction as an addition to the usual pharmacological treatment.
