摘　　要：目的通过心电图与心电向量图同时记录,及时发现左后分支阻滞。方法选择有临床表现、心电向量图诊断明确的5例左后分支阻滞进行分析。结果 5例左后分支阻滞的心电向量图表现以F面最大向量向右下偏移为主要特点。结论心电向量图在诊断左后分支阻滞方面明显优于心电图,无论哪个版本的左后分支阻滞的心电图诊断标准,在没有心电向量图证实的情况下可靠性都较差,诊断时应持慎重态度,二者结合可以提高诊断的准确性。Objective To identify left posterior branch block in time,by recording its electrocardio- gram（ECG） and vectorcardiogram（VCG） simultaneously. Methods Five cases of left posterior branch block were taken into analysis, which had clinical manifestations and specific diagnostic results by VCG. Results The VCGs of 5 cases with left posterior branch block were mainly characterized by the F maxi- mum vector shifting to the bottom right. Conclusion In the diagnosis of left posterior branch block,VCG is obviouly superior to ECG. Without the verification of VCG,the reliability of ECG diagnostic criterion of left posterior branch block is poor,regardless of its version. Therefore ,cautiousness is a must in ECG di- agnosis. A combination of ECG and VCG can improve the accuracy of diagnosis.
