Supraventricular tachycardia in a patient receiving ECT, clozapine, and caffeine

M D Beale et al. Convuls Ther. 1994 Sep.

Abstract

A patient receiving electroconvulsive therapy (ECT), clozapine, and intravenous caffeine sodium benzoate developed supraventricular tachycardia. This was rapidly treated with intravenous verapamil. Subsequent maintenance ECT given without caffeine was well tolerated. We believe the combination of clozapine and caffeine at the time of ECT was responsible for the arrhythmia.
