目的分析心电图对陈旧性心肌梗死的诊断价值及漏诊原因。方法 120例心肌梗死患者,予以心电图检查,心电图异常者结合生化检查及超声心动图检查,对其检查结果进行回顾性分析。结果 120例心肌梗死经心电图检查均发现异常波,其中异常Q波占百分比为13.33%(16/120),而心电图异常Q波中陈旧性心肌梗死患者占的百分比为93.75%(15/16)。结论心电图在陈旧性心肌梗死诊断中有良好的诊断鉴别价值,心电图出现异常Q波未加仔细鉴别是导致漏诊的主要原因。
Objective To analyze the diagnostic value and cause of missed diagnosis of old myocardial infarction by electrocardiogram. Methods A total of 120 patients with myocardial infarction were examined by electrocardiogram (ECG), electrocardiogram (ECG) abnormalities combined with biochemical examination and echocardiography, and retrospectively analyzed the examination results. Results The abnormal wave was detected by electrocardiogram in 120 cases of myocardial infarction. The percentage of abnormal Q wave was 13.33% (16/120), while the percentage of old myocardial infarction in Q wave of abnormal electrocardiogram was 93.75% (15/16) . Conclusion Electrocardiogram has a good diagnostic value in the diagnosis of old myocardial infarction. The abnormal ECG Q wave without careful identification is the main reason leading to missed diagnosis.
