We present a case of a patient with drug resistant atrial tachycardia which was ablated from the noncoronary aortic cusp. Tachycardia was adenosine-sensitive and was characterized by a long RP' interval and low amplitude P waves (biphasic in II, III, aVF and V1-V2 leads, and positive in aVL). The earliest atrial activation during tachycardia was recorded at His region and from non-coronary aortic sinus of Valsalva. RF ablation at this area terminated tachycardia and did not impair atrio-ventricular conduction.
我们报告一例耐药性房性心动过速患者，其心动过速起源于非冠状动脉主动脉瓣窦并接受了消融治疗。心动过速对腺苷敏感，其特征为RP'间期长和P波振幅低（在II、III、aVF及V1 - V2导联呈双向，在aVL导联为正向）。心动过速时最早的心房激动记录于希氏束区域及非冠状动脉瓦尔萨尔瓦窦。在此区域进行射频消融终止了心动过速，且未损害房室传导。
