摘要

目的:观察导管射频消融治疗局灶性房性心动过速的疗效及安全性

并比较常规标测与Carto系统标测的结果差异。方法:50例局灶性房性心动过速患者进行了电生理检查和射频消融治疗

32例采用常规标测

25例采用Carto系统标测（包括常规标测消融失败的7例）。平均随访20±11月

观察常规标测组和Carto系统标测组射频消融即刻和远期成功率及安全性和临床症状改善情况

同时比较二组"射线暴露时间。结果:①常规标测组和Carto系统标测组射频消融即刻成功率分别为78%、100%

远期成功率分别为68%、96%

无1例发生并发症;成功术后

由局灶性房性心动过速引起的症状消失。②Carto系统标测组%射线暴露时间明显少于常规标测组。结论:局灶性房性心动过速射频消融治疗成功率和安全性高

Carto系统标测比常规标测更有优势

且明显减少X射线暴露时间。

Abstract

Objective:To investigate the efficacy and safety of catheter radiofrequency ablation for focal atrial tachycardia

by comparing conventional mapping group and Carto system mapping group.Methods:50 patients with focal atrial tachycardia underwent electrophysiologic study and radiofrequency ablation.32 cases were in conventional mapping group

and 25 cases in Carto system mapping group

including 7 cases with unsuccessful ablation in conventional mapping group.During follow-up 20±11 months

radiofrequency ablation acute successful rate

long-term successful rate

safety

and the clinical symptoms were recorded.ⅹ-ray radiation exposure time was compared between conventional mapping group and Carto system mapping group.Results: ① radiofrequency ablation acute successful rate of conventional mapping group and Carto system mapping group were 78% and 100%

and long-term successful rate were 68% and 96% respectively.No complications occurred.The clinical symptoms caused by focal atrial tachycardia disappeared after successful ablation.② ⅹ-ray radiation exposure time of Carto system mapping group was shorter than that of conventional mapping group.Conclusions: Successful rate and safety of radiofrequency ablation of focal atrial tachycardia were higher

and effects of Carto system mapping group were better than those of conventional mapping group.And X-ray radiation exposure time of Carto system mapping group decreased.
