心电图诊断左房肥大的6个标准敏感性相对分散(15%～83%),而特异性较高(64%～100%)。6个诊断标准中,以Morris指数的诊断价值最高,其敏感性达76%,特异性为92%。
The six standard sensitivities of ECG in diagnosis of left atrial hypertrophy were relatively decentralized (15% -83%) and high specificity (64% -100%). Of the six diagnostic criteria, the Morris index was the most valuable diagnostic value with a sensitivity of 76% and a specificity of 92%.
