摘要(Abstract)：

目的比较冷冻导管消融与射频消融治疗房室结折返性心动过速的有效性和安全性。方法回顾性分析中国医科大学附属第四医院2014年6月至2016年5月122例房室结折返性心动过速行导管消融术的患者,其中冷冻导管消融组56例,采用8 mm冷冻大头消融导管;射频消融组66例。比较两组患者成功率、复发率、房室传导阻滞发生率、手术时间及X线曝光量的情况。结果两组患者年龄、性别、器质性心脏病史、手术成功率比较,差异均无统计学意义(均P>0.05);但射频消融组患者手术时间[(70.00±7.50)min比(66.29±4.72)min,P=0.001]、X线曝光量[(837.52±138.38)m Sv比(674.14±126.12)m Sv,P<0.001]显著大于冷冻导管消融组,差异均有统计学意义。结论采用8 mm冷冻大头导管消融治疗房室结折返性心动过速安全有效,较普通射频消融术有潜在优势。
