摘　　要：目的采用立体心电图仪通过Wilson和Frank双导联体系采集心电图和心电向量图,及时诊断和鉴别诊断心电轴左偏所致的疾病。方法选择有临床表现,心电图诊断明确的心电轴左偏的病例,进行心电向量图分析和鉴别诊断。结果5例心电图图形相似,均表现为心电轴左偏,但心电向量图的表现及诊断各不相同。结论心电向量图在诊断和鉴别诊断心电轴左偏所致疾病时,有一定优势;心电轴左偏在没有心电向量图证实的情况下,诊断所致疾病时,应持慎重态度。在实际工作中,心电图与心电向量图应采取优势互补的原则,取长补短,服务于临床,二者结合可以提高心电学诊断的准确性。Objective Electrocardiogram(ECG)and vectorcardiogram(VCG)were collected by Wilson and Frank dual lead system.The diseases caused by left deviation of ECG axis were timely identified.Methods The symptomatic patients with left deviation of ECG were selected and their ECGs and VCGs were analyzed.Results Five cases were similar in ECG pattern,and all of them showed left axis deviation.But the performance and diagnosis of VCG were different.Conclusion VCG showed better performance in the diagnosis of diseases caused by left deviation of electrocardiogram axis compared to ECG.It should be careful when identify the diseases caused by left deviation of electrocardiogram axis without the help of VCG.We should combine the advantages of both ECG and VCG,to well serve the clinic application and improve the accuracy of diagnosis.
