摘要:
目的:报告经主动脉无冠状窦内射频消融6例局灶性房性心动过速(房速)的消融结果。方法： 6例患者中男女各3例。阵发性房速病史(6±3)年。常规心电图、心内电生理，术中心房和心室刺激诱发房速，分别在右心房、左心房和主动脉无冠状窦内标测最早心房激动，并进行射频消融。结果： 心房刺激能反复诱发和终止6例患者的房速。心房内的前间隔部位标测相对提前的心房激动，但多次消融未成功。经主动脉无冠状窦内消融成功。平均随访3～17个月，无1例房速复发。结论： 经主动脉无冠状窦消融前间隔房速是安全，有效的。
Abstract:
AIM:To report successful catheter ablation of anteroseptal focal atrial tachycardia (AT) from the aortic non-coronary sinus cusp. METHODS: Six patients ［three males and three females with paroxysmal AT for (6±3) years］ were mapped and ablated in both atria and aortic non-coronary sinus cusp. RESULTS: ATs were easily reproducibly induced and terminated by atrial pacing in the six patients. Multiple radiofrequency ablation at the anteroseptal region of the atria failed. However, mapping in the aortic non-coronary sinus was successful. All six patients were free of AT during the following 3 to 17 months. CONCLUSION: Mapping and ablation from the aortic non-coronary sinus cusp is a safe and effective approach, especially when ablation of AT fails at the bundle region.
