title: Coexistence of 2 types of atrial tachycardias and right ventricular outflow tract tachycardia.
abstract: Double tachycardia is a relatively uncommon type of tachycardia. In this report, we discuss a 68-year-old woman with history of frequent palpitations. Electrophysiologic study revealed that narrow QRS tachycardias from 2 origins and 1 wide QRS tachycardia were induced and each of the tachycardias was induced by the other. We found that 2 focal atrial tachycardias and 1 ventricular tachycardia originated from right ventricular outflow tract. All of these tachycardias were successfully ablated during one session, and no recurrence appeared during 10 months of follow-up.
