摘要
目的：分析三维标测指导下射频消融治疗阵发性室上性心动过速的临床价值。方法选取来本院就诊的168例阵发性室上性心动过速患者，将其随机分为实验组和对照组两组，每组84例。实验组采用三维标测对心室标测并指导消融；对照组在 X线透视下标测并指导消融，比较两组消融成功率、复发率、曝光时间及放电次数等。结果实验组消融成功率为96．4％；对照组消融成功率为90．4％，可见实验组消融成功率更高；实验组曝光时间短于对照组[实验组（16±7）min；对照组（37±17）min]，实验组放电次数少于对照组[实验组（3±1）n；对照组（5±4）n]。对两组消融成功患者进行随访，实验组复发率为4．7％；对照组复发率为14．3％，对照组复发率明显高于实验组。结论三维标测指导下射频消融治疗阵发性室上性心动过速有较理想的应用价值，值得临床研究推广。
Abstract
Objective Analysis of three-dimensional mapping and ablation of paroxysmal supraventricular heartbeat too fast under the guidance of the clinical val-ue of radio frequency.Methods 168 patients with paroxysmal chamber to the hospital on the heartbeat tachycardia patients randomly divided into experimental group and control group two groups,each group of 84 cases.The experimental group used three-dimensional mapping of ventricular mapping and catheter ablation;control group in X-ray fluoroscopy subscript measured and compared between the two groups of catheter ablation,ablation success rate,recurrence rate,exposure time and discharge time etc.Results The success rate of ablation was 96.4%;the control group of successful ablation rate was 90.4%,while in the experimental group,the success rate was high-er in experimental group;the exposure time was shorter than the control group[(16 ±7)in experimental group min;the control group(37 ±17)min],the experimental group and discharge times less than that of the control group[group(3 ±1)n;control group(5 ±4)n].The two groups were followed up successfully ablated patients in experimental group,the recurrence rate was 4.7%;the control group the recurrence rate was 14.3%,the control group was significantly higher than that in the experi-mental group the recurrence rate.Conclusion Catheter ablation for paroxysmal supraventricular tachycardia with heartbeat value ideal guided radiofrequency three -di-mensional mapping,is worthy of clinical research.
