Abstract:
A 31 year old woman who developed an atypical ventricular tachycardia after administration of intravenous verapamil for control of a recurrent supraventricular tachycardia is presented. Possible explanations for the observed arrhythmia, polymorphous ventricular tachycardia, are discussed. Verapamil must be considered one of the pharmacologic agents that can cause this arrhythmia.
