【摘要】 目的 探讨心电向量图和心电图对陈旧性下壁心肌梗死诊断的价值。方法 对比分析65例临床确诊为陈旧性下壁心肌梗死患者的心电向量图和心电图。结果 心电向量图准确率为60%，心电图准确率为33.8%，差异有非常显著性(P<0.01)。结论 对陈旧性下壁心肌梗死的诊断中心电向量图准确率高于心电图，故临床工作中对陈旧性下壁心肌梗死心电图诊断有疑虑时，应行心电向量图检查，有助于明确诊断。

    【Abstract】 Objective To evaluate the features of vector cardiographic (VCG) and electrocardiography (ECG) in the diagnosis of inferior wall post-acute myocardial infarction.Methods Analyze 65 cases of the inferior wall post-acute myocardial infarction patients’ VCG and ECG.Results Only 33.8% ECGs shows inferior wall pose-acute myocardial infarction,but,in the VCG 60% signs inferior wall pose-acute myocardial infarction (P<0.01).Conclusion VCG is preciser than ECG in the diagnosis of post-acute myocardial infarction.VCG should be examined if there is any uncertain about post-acute myocardial infarction in clinic findings. ......
