Key result
A slow intravenous bolus of potassium chloride successfully restored sinus rhythm in a patient with a hemodynamically unstable ventricular tachycardia storm refractory to standard antiarrhythmic medications.
Why the study?
Does a slow IV bolus of potassium chloride resolve refractory ventricular tachycardia storm in a patient with hypokalemia?
Case Report (n=1)

Does a slow IV bolus of potassium chloride resolve refractory ventricular tachycardia storm in a patient with hypokalemia?
A slow IV bolus of potassium chloride successfully resolved a life-threatening, refractory ventricular tachycardia storm associated with hypokalemia in a patient with acute myocardial infarction.
May support potassium repletion in hypokalemic refractory VT storm; hypothesis-generating case report requiring prospective validation.
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.

Sella et al. (2018) conducted a case report in Ventricular Tachycardia Storm (n=1). Intravenous Potassium Chloride was evaluated on Resolution of Ventricular Tachycardia Storm. A slow intravenous bolus of potassium chloride successfully restored sinus rhythm in a patient with a hemodynamically unstable ventricular tachycardia storm refractory to standard antiarrhythmic medications.
