摘　　要：目的探讨正交心电图对左心房肥大的诊断价值。方法观察以超声心动描记术诊断的144例左心房正常人和124例左心房增大患者的正交心电图并与常规心电图比较。结果正交心电图与左心房前后径有直线相关关系。正交心电图综合标准和简化标准诊断左房肥大的敏感性、准确性和阴性预测性分别为83.1%、82.1%、84.8%和79.8%、81.75%、82.6%(p>0.05),显著高于常规心电图的51.6%、71.3%、67.9%(p>0.01)。结论认为正交心电图简化标准操作简便,是一种较好的诊断左心房肥大的方法。Objective to study the diagnostic value of orthogonal electocardiogram in left atrial enlargement.Methods The orthogonal electrocardiokgram were recorded in124patients with left atrial atrial enlargement and compare with144healthly.Results The sensitivites,speciticities and negative predictive value of the simplified standard in diagnosis of orthogonal electrocardiogram,were83.1%,82.1%and84.8%respectively,compared with those of the multiple standard(p>0.05),but compared with those(51.6%,71.3%and67.8%)of electrocardiogram((p>0.05).Conclusion The orthogonal electrocardiogram seems to be a better method for detecting left atrial elargement than electrocardiogram.
