摘要目的探讨Carto3三维标测系统指导下低射线射频消融阵发性室上性心动过速的可行性、安全性与优势。方法选取2015年2月～2017年11月我院收治的65例阵发性室上性心动过速（PSVT）患者作为研究对象，随机分为二维组（29例）和三维组（36例）。二维组在常规X线照射下采用普通二维方法行射频消融治疗，三维组在Carto3系统指导下低射线的射频消融治疗，比较两组患者的PSVT类型、手术时间、X线曝光时间及曝光量、并发症发生率。结果两组患者均成功完成手术，其中二维组中有1例房室结双径路患者术中发生一过性Ⅲ度房室传导阻滞。两组患者的总手术时间比较，差异无统计学意义（P＞0.05）；三维组的X线曝光时间及曝光量少于二维组，差异有统计学意义（P＜0.05）。结论Carto3三维标测系统引导下低射线射频消融阵发性室上性心动过速是安全可行的，可减少医生和患者的放射性损伤。

Abstract：ObjectiveTo discuss the the feasibility,safety and advantages of Carto3 three-dimensional mapping system in guiding radiofrequency ablation for paroxysmal supraventricular tachycardia under low-dose radiation.MethodsA total of 65 patients with paroxysmal supraventricular tachycardia(PSVT)treated in our hospital from February 2015 to November 2017 were selected as the subject,and randomly divided into 2D group　(29 cases)and 3D group　(36 case).The 2D group used conventional X—Ray guide ablation,and the 3D group used Carto3 under low-dose radiation guide ablation.The PSVT type,operation time,X-ray exposure time,X-ray fluoroscopy time and complication rates were compared between the two groups.ResultsAll procedures were actely successful,but one patient in the 2D group was developed transient degreeⅢatrioventricular block during ablation.There was no statistically significant difference in the total operation time between the two groups(P＞0.05).The X-ray exposure time in 3D group was shorter than 2D group,and X-ray fluoroscopy time in 3D group were less than 2D group,the differences were statistically significant(P＜0.05).ConclusionRadiofrequency ablation of paroxysmal supraventricular tachycardia with the help of the Carto3 three-dimensional mapping system under low-dose radiation is safe and feasible，and is helpful to reduce the radiation injury of the doctors and patients.
