摘　　要：背景近年随着科学技术不断发展,高功率短时程导管射频消融心房颤动(AF)逐渐应用于临床,但目前有关高功率短时程导管射频消融的实际消融功率值尚未确定。目的比较高功率短时程与常规功率导管射频消融治疗AF的有效性和安全性。方法本研究为回顾性研究。随机选取2020年安徽医科大学第一附属医院收治的行高功率短时程导管射频消融治疗(前壁消融功率为50 W,其他部位消融功率为40 W)的42例AF患者作为高功率组,行常规功率导管射频消融治疗(前壁消融功率为35 W,其他部位消融功率为30 W)的42例AF患者作为常规功率组。比较两组患者消融效果,主要包括环肺静脉电隔离术(CPVI)成功率、CPVI中补点消融发生率及消融时间;比较两组患者导管射频消融术后并发症发生率及术后12个月内AF复发率。结果两组患者CPVI成功率和CPVI中补点消融发生率比较,差异无统计学意义(P>0.05);高功率组患者消融时间短于常规功率组(P<0.05)。两组患者平均随访(135.7±98.9)d,均未发现导管射频消融术后并发症。两组患者术后12个月内AF复发率比较,差异无统计学意义(P>0.05)。结论与常规功率导管射频消融相比,高功率短时程导管射频消融能更有效地缩短AF患者消融时间,且未增加术后并发症及AF复发风险,故高功率短时程导管射频消融是一种有效、安全的消融术式。Background In recent years,with the continuous development of science and technology,the highpower short duration radiofrequency catheter ablation to atrial fibrillation(AF)is gradually used in clinical practice,but its actual ablation power has not been determined.Objective To compare the effectiveness and safety of high-power short duration radiofrequency catheter ablation and conventional-power radiofrequency catheter ablation for AF.Methods This study is a retrospective study.In 2020,42 AF patients who received high-power short duration radiofrequency catheter ablation(50 W ablation power in anterior wall and 40 W ablation power in other parts)were randomly selected as high-power group,and 42 AF patients who received conventional-power radiofrequency catheter ablation(35 W ablation power in anterior wall and 30 W ablation power in other parts)were randomly selected as the conventional-power group.The ablation effect was compared between the two groups,including the success rate of circumferential pulmonary vein isolation(CPVI),incidence rate of patching ablation of CPVI and ablation time;and the postoperative complications of radiofrequency catheter ablation the recurrence rate of AF 12 months after operation were compared between the two groups.Results There was no significant difference in the success rate of CPVI and incidence rate of patching ablation of CPVI between the two groups(P>0.05);the ablation time in the high-power group was shorter than that in the conventional-power group(P<0.05).The average followup time of the two groups was(135.7±98.9)days,and there were no postoperative complications of radiofrequency catheter ablation were found.There was no significant difference in the recurrence rate of AF 12 months after operation between the two groups(P>0.05).Conclusion Compared with conventional-power catheter radiofrequency ablation,high-power short duration radiofrequency catheter ablation can more effectively shorten the ablation time of patients with AF,and it don't increase the risk of postop
