Ebstein's anomaly is highly associated with atrioventricular reciprocating tachycardia (AVRT) due to an atrioventricular accessory pathway (AP). This case report describes a case of a 30-year-old man with Ebstein's anomaly who had been suffering from recurrent palpitation caused by AVRT due to the right-sided AP. Conventional mapping technique failed to ablate his AP successfully. In baseline electrophysiological study, orthodromic AVRT with a right posterior AP were induced. The AP was mapped using an electroanatomic mapping system. RF current was successfully delivered at the posterior site. RFCA using an electroanatomic mapping system seems to be useful for A VRT patients in Ebstein's anomaly.
埃布斯坦畸形与因房室旁道（AP）导致的房室折返性心动过速（AVRT）高度相关。本病例报告描述了一名30岁患有埃布斯坦畸形的男性患者，他因右侧AP导致AVRT反复发作心悸。传统标测技术未能成功消融其AP。在基线电生理研究中，诱发了伴有右后AP的顺向性AVRT。使用电解剖标测系统对AP进行标测。射频电流成功地施加于后部位置。对于埃布斯坦畸形合并AVRT的患者，使用电解剖标测系统进行射频导管消融似乎是有效的。
