Polymorphic ventricular tachycardia in a woman taking cesium chloride

Pacing Clin Electrophysiol. 2001 Apr;24(4 Pt 1):515-7. doi: 10.1046/j.1460-9592.2001.00515.x.

Abstract

A 47-year-old patient presented with syncope and recurrent episodes of polymorphic ventricular tachycardia. She had evidence of prolonged QT interval by ECG and had been taking cesium as a dietary supplement. Correction of the hypokalemia and discontinuation of the cesium resulted in normalization of the QT interval during follow-up with no further recurrence of ventricular arrhythmias. The use of this drug is potentially hazardous as it may induce fatal ventricular arrhythmias.
