Speech-induced atrial tachycardia: an unusual presentation of supraventricular tachycardia.

A 63-year-old male radio announcer was admitted with a narrow complex, long RP tachycardia. While in the awake state, the patient spoke in his radio voice, initiating and maintaining the tachycardia. Three-dimensional electroanatomic mapping during electrophysiology study localized the tachycardia to the ostium of the right superior pulmonary vein. After single radiofrequency energy application, no further arrhythmias were inducible with speech. At more than 1 year of follow-up, the patient had no recurrences and continues to work as a radio announcer.
