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、成功率及并发症发生情况.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,两组成功率差异无统计学意义.CARTO组与常规组手术时间无差异[（118±36）min比（119±52）min,P＞0.05],但X线曝光时间明显缩短[（9±3）min比（17±6）min,P＜0.05],放电次数显著减少[（4±2）次比（9±3）次,P＜0.05],放电时间显著缩短[（196±73）s比（402±84）s,P＜0.05].两组患者均未发生并发症.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 electroanatomie mapping and conventional electrophysiological mapping under X-ray and to evaluate the guiding effect of CARTO system radiofrequency abla- tion of supraventricular tachycardia. Methods The objects consisted of 118 patients with supraventricular tachy- cardia, according fact therapy methods divided into CARTO mapping group （n=69） and conventional group （n=49）. The fluoroscopy time, operation time, discharging number and discharging t/me and occurrence of complications were compared between two groups. Results There was no difference in success 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±6）m in,P〈0.05 ] than conventional group, and for overall discharging number significantly decreased [ （4±2） vs （9±3）, P〈0.05 ] and discharging time [ （ 196±73 ）s vs （402±84） s, P〈0.05 ]. Conclusion Radiofrequeney ablation of supraventrieular tachycardia by the CARTO eleetroanatomic mapping system is safe and effective.
