摘要 目的:观察并分析心电图对左心室肥厚的诊断敏感性与特异性。方法:选取350例来本院接受心电图检查的患者,以左心室重量指数大小为依据,将所有患者分成两组,阳性组71例,阴性组279例,分析并评价各项诊断指标的敏感性与特异性。结果:在左心室肥厚的诊断中,Sokolow、Cornell电压及Cornell乘积等指数的敏感性均不超过50%,但特异性均达到86%以上,其中最高的是Cornell电压指数,数据差异有统计学意义(P<0.05)。结论:在左心室肥厚的心电图诊断中,Cornell电压指数的诊断特异性较好。 Objective:To observe and analyze the diagnostic sensitivity and specificity of electrocardiogram for left ventricular hypertrophy.Methods:Select 350 patients who came to our hospital for electrocardiogram examination,and divide all patients into two groups based on the size of the left ventricular mass index,71 cases in the positive group and 279 cases in the negative group.With specificity.Results:In the diagnosis of left ventricular hypertrophy,the sensitivity of indexes such as Sokolow,Cornell voltage and Cornell product did not exceed 50%,but the specificity reached more than 86%,the highest of which was the Cornell voltage index,the data difference was statistically significant Significance(P<0.05).Conclusion:In the electrocardiographic diagnosis of left ventricular hypertrophy,the diagnostic specificity of Cornell voltage index is better.
