目的：评价单次或多次进行单独肺静脉隔离术或联合复杂碎裂电位消融的长期疗效。方法：用计算机检索PubMed、EMbase、Cochrane Library、知网、万方、维普等数据库，英文检索词有Atrial Fibrillations、Catheter Ablation、Complex Fractionated Electrograms，中文检索词有房颤、导管消融、复杂碎裂电位。检索日期截止至2018年10月，纳入关于单独肺静脉隔离术与联合复杂碎裂电位消融的前瞻性随机对照试验，采用RevMan5.3软件进行meta分析。结果：与单独肺静脉隔离术相比，单次额外的复杂碎裂电位消融并没有改善术后窦性心律的维持率[RR=1.04，95%CI（0.93，1.15），P=0.50]，重复手术也没有改善术后窦性心律的维持率[RR=1.00，95%CI（0.93，1.08），P=0.98]，但术后发作的房性心律失常以房扑和房性心动过速为主[RR=2.12，95%CI（1.64，2.74），P<0.000 01]，且增加了手术时间、透视时间及消融时间。结论：额外的复杂碎裂电位消融没有改善术后窦性心律维持率，但降低了房颤的复发率，增加了手术时间、透视时间和消融时间。
