摘　　要：目的:对比三维电磁导管标测(Carto)系统与常规方法指导射频消融治疗阵发性室上性心动过速(PSVT)的效果。方法:选取2019年5月-2021年5月景德镇市第二人民医院收治的60例PSVT患者作为研究对象,发放随机信封根据单双号分组,每组30例。对照组予以常规方法指导射频消融治疗,观察组予以Carto系统指导治疗。比较两组手术时间、X线辐射时间及辐射量、随访手术成功率及并发症发生率。结果:两组手术时间比较,差异无统计学意义(P>0.05);观察组X线辐射时间、辐射剂量均少于对照组,差异均有统计学意义(P<0.05)。观察组手术即时成功率高于对照组,复发率低于对照组,差异均有统计学意义(P<0.05)。观察组术后并发症发生率为6.7%,低于对照组的26.7%(P<0.05)。结论:应用Carto系统指导射频消融治疗PSVT患者,有利于减少X线辐射时间及辐射剂量,在提升手术即时成功率、降低并发症方面有着突出的效果,可予以推广。Objective:To compare the effect of radiofrequency ablation for paroxysmal supraventricular tachycardia (PSVT) guided by three-dimensional electromagnetic catheter mapping (Carto) system and conventional methods in the treatment of paroxysmal supraventricular tachycardia.Method:A total of 60 PSVT patients admitted to the Second People’s Hospital of Jingdezhen from May 2019 to May 2021 were selected as the study subjects,random envelopes were distributed according to single and double number grouping,30 cases in each group.The control group was given radiofrequency ablation guided by conventional methods and the observation group was given radiofrequency ablation guided by Carto system.The operation time,X-ray radiation time and radiation amount,the immediate success rate of operation and the incidence of complications were compared between two groups.Result:There was no significant difference in the operation time between two groups (P>0.05).The X-ray radiation time and radiation amount in the observation group were less than those in the control group,the differences were statistically significant (P<0.05).The immediate success rate of operation in the observation group was higher than that in the control group,and the recurrence rate was lower than that in control group,the differences were statistically significant (P<0.05).The incidence of postoperative complications in the observation group was 6.7%,which was lower than 26.7% in the control group (P<0.05).Conclusion:The application of Carto system to guide radiofrequency ablation for PSVT patients is beneficial to reduce X-ray radiation time and radiation dose,and has outstanding effects in improving the immediate success rate of operation and reducing complications,which can be popularized.
