目的分析 CARTO 系统标测下射频消融治疗特发性室性心动过速（室速）的临床应用价值。方法选取2011年5月至2013年7月来本院就诊的200例特发性室速患者，将其随机分为观察组和对照组两组，每组100例。观察组采用 CARTO 系统对心室标测，显示心室三维电激动图并指导消融；对照组在常规 X 线透视下标测并指导消融，比较两组的即时成功率、复发率、手术时间、曝光时间及放电次数等。结果观察组有63例左心室室速，37例右心室室速，98例消融成功，2例失败，消融成功率为98%；对照组中有66例左心室室速，34例右心室室速，89例消融成功，11例失败，消融成功率为89%，两组手术时间无明显差异[观察组（221±57）min；对照组（208±66）min]，观察组曝光时间短于对照组[观察组（15±6）min；对照组（36±18）min]，观察组放电次数少于对照组[观察组（3±2）n；对照组（5±6）n]。对两组消融成功患者进行为期3~24个月的随访，观察组5例复发，复发率为5.1%；对照组13例复发，复发率为14.6%，均再次消融成功。结论 CARTO 标测下射频消融治疗特发性室速准确可靠，可明显缩短曝光时间，减少放电次数，值得临床进一步研究推广。

Objective To analyze the mapping of radiofrequency catheter ablation of idiopathic ventricular heartbeat tachycardia (VT) CARTO system the value of clinical application. Methods From 2010 May ~2012 year in July in our hospital 200 cases of idiopathic ventricular tachycardia patients, Randomly divided into observation group and control group two groups, Each group of 100 cases. The observation group was treated with CARTO system mapping on ventricular, Showed ventricular three-dimensional electrical activation map and guide catheter ablation; Control group in conventional X-ray subscript measured and compared between the two groups of ablation, Instant success rate, recurrence rate, operation time, exposure time and discharge time etc.Results In the observation group, 63 cases of left ventricular tachycardia, 37 cases of right ventricular tachycardia, 98 cases of successful ablation, failure in 2 cases, ablation success rate was 98%; 66 cases of left ventricular rate in the control group, 34 cases of right ventricular tachycardia, 89 cases of successful ablation, 11 cases of failure, success rateof ablation 89%, The two groups had no significant difference in operation time [the observation group (221 ± 57) min; control group (208 ± 66) min], The observation group exposure time was shorter than the control group [(15 ± 6) study group min; the control group (36 ± 18) min], Discharge times less than that of the control group, the observation group (3 ± 2) n; control group (5 ± 6) n]. On two groups of successful ablation patients for a period of 3~24 months of follow-up, the observation group of 5 cases of recurrence, The recurrence rate was 5.1%; the control group of 13 cases of recurrence, The recurrence rate was 14.6%, all successful ablation. Conclusion CARTO mapping radiofrequency catheter ablation of idiopathic ventricular tachycardia isaccurate and reliable, Can significantly shorten the exposure time, Reduce the discharge times, worthy of further clinical study.
