A case report of bidirectional ventricular tachycardia secondary to aconitum toxicity

Abstract

We present a case of malignant ventricular arrhythmia secondary to unintentional aconite poisoning. Healthcare workers need to be vigilant regarding cases of aconitum toxicities, especially in atypical presentations. There is also a need to educate the public regarding the consumption and preparation of potent TCM herbs that may result in lethal toxicity.

Keywords: aconitum; toxicity; ventricular tachycardia.
