CARTO电解剖标测系统指导下射频消融室上速的研究

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），比较两纽标测与消融过程的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，两组成功率无显著性差异，CARTO组较常规组在手术时间中无显著性差异（118±36minVS119±52min，P〉0．05），但在X线曝光时间明显缩短（9±3minVS17±6rain，P〈0．05）、放电次数显著减少（4±2次VS9±3次，P〈0．05）、放电时间显著缩短（196±73sVS402±84s，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。

Radiofrequency Ablation of Supraventricular Tachycardia by the CARTO Electroanatomic Mapping System

Objective To compare the efficacy of CARTO electroanatomic mapping and conventional electrophysiological mapping under X-ray and to evaluate the guiding effect of CARTO systemon radiofrequency ablation of supraventricular tachycardia. Methods 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 occurrencce of complications 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±3min VS 17±6min, 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 VS 2102±84, P〈0.05）.Conclusion Radiofrequency ablation of supraventricular tachycardia by the CARTO electroanatomic mapping system Was safe and effective.
