Automatic junctional tachycardia is frequently refractory to medical management and difficult to treat with nonpharmacological methods. A 12-year-old female with symptomatic, refractory automatic junctional tachycardia is reported. Earliest atrial activation during supraventricular tachycardia was in the posterior portion of the intraatrial septum. The patient underwent electrophysiological study and successful radiofrequency current ablation of the ectopic automatic focus within the atrioventricular junction. Normal atrioventricular junctional conduction was maintained, and at 7-month follow-up the patient has been free of tachycardia.
自主性交界性心动过速常常对药物治疗无效，且难以用非药物方法治疗。本文报道了一名患有症状性、难治性自主性交界性心动过速的12岁女性。室上性心动过速期间最早的心房激动位于房间隔后部。该患者接受了电生理检查，并成功地对房室交界区内的异位自律焦点进行了射频电流消融。房室交界区的正常传导得以维持，在7个月的随访中，患者未再出现心动过速。
