摘　　要：目的:评价CARTO电解剖标测系统对射频消融室上速的指导作用。方法:118例室上速患者分为CARTO组(69例)和常规组(49例),比较两组标测与消融过程的X线曝光时间、手术时间、放电次数、放电时间及成功率、并发症发生情况。结果:118例均完成射频治疗,2例常规射频失败患者转为CARTO指导下成功完成治疗,两组成功率比较,差异无统计学意义(P>0.05),CARTO组较常规组在手术时间中比较,差异无统计学意义(118±36 min VS 119±52 min,P>0.05),但在X线曝光时间明显缩短(9±3 min VS 17±6 min,P<0.05)、放电次数显著减少(4±2次VS 9±3次,P<0.05)、放电时间显著缩短(196±73 s VS402±84 s,P<0.05)。均无并发症出现。结论:CARTO电解剖标测系统指导下射频消融室上速安全有效,可明显减少放电次数和时间,缩短X线曝光时间。Objective To compare the efficacy of CARTO electroanatomic mapping and conventional eleetrophysiological mapping under X - ray and to evaluate the guiding effect of CARTO systemon radiofrequency ablation of supraventricular tachycardia. Method The objects consisted of 118 patients with supraventricular tachycardia, according fact therapy methods dicided into CARTO mapping group （ n = 69 ） and conventional group（ n = 49 ） ,The fluoroscopy time 、 operation time、discharging number and discharging time and occurrence of compli- cations were compared between two groups. Results There was no difference in sucees rate and operation time between two groups （ P 〈 0. 05 ）, While CARTO group used the mean fluoroscopy time Was significantly shorter （9 ± 3 min VS 17±6min,P 〈 0. 05 ） than convention- al group, and for overall discharging number si guificantly decreased （ 4 ± 2 VS 9 ±3, P 〈 0.05 ） and discharging time （ 196 ± 73 VS 402 ±84,P 〈 0. 05）. Condusion Radiofrequency ablation of supraventricuJar tachycardia by the CARTO electroanatomic mapping system is safe and effective.
