A rare case of bidirectional ventricular tachycardia due to aconite poisoning

Abstract

A 45-year-old female patient presented with sweating and palpitation with wide spectrum of electrocardiography changes from polymorphic ventricular ectopics to bidirectional ventricular tachycardia (VT). She had a concealed history of aconite intake in large doses as part of homeopathic use. There are very few causes of bidirectional tachycardia such as digitalis toxicity, catecholaminergic polymorphic VT, and rarely aconite poisoning. Here, we report a rare case of aconite poisoning presenting with bidirectional VT.
