摘　　要：目的观察受检者完全性左束支阻滞的发生率及心电图特点。方法记录和分析86621例常规12导联同步心电图,分别统计完全性左束支阻滞(CLBBB)及右束支阻滞(RBBB)的发生情况及心电图特点。结果检出完全性左束支阻滞(CLBBB)170例,占0.19%;检出RBBB3243例(男2252例,年龄4～98岁;女991例,年龄2～96岁),占3.74%;完全性右束支阻滞(CRBBB)1587例,占1.83%。RBBB是CLBBB的19倍。有1806例RBBB合并其他心律失常,占55.7%。结论 RBBB较常见,CLBBB不多见。CLBBB合并急性心肌梗死心电图诊断须慎重。Objective To observe the incidence and ECG characters of complete left branch bundle block.Methods Recorded the 12-lead synchronous ECG of 86621 cases,analyzed ECG characters and the incidence of left branch bundle block and right branch bundle block.Results 170 cases of CLBBB were detected（0.19%）,3243 cases（male 2252 cases,age 4 to 98;female 991cases,age 2 to 96）of RBBB were detected（3.74%）;1587 cases of CRBBB were detected（1.83%）.1806 cases of RBBB with other arrhythmias（55.7%）.Conclusions RBBB is more common than LBBB.CLBBB with AMI ECG diagnosis need carefulness.
