多项心电图标准诊断左心室肥厚准确性的对比观察

Comparative Study of the Accuracy of Diagnosis of Left Ventricular Hypertrophy with Multiple ECG Criterions

目的 :探讨多项心电图标准诊断左心室肥厚的准确性。方法 :以彩色多普勒超声心动图仪为对照 ,观察 113例 、 期原发性高血压病患者的心电图 ,比较多项诊断左心室肥厚的心电图标准 ,结果 :纽约心脏病学会标准敏感性最高为 44 .87% ,而特异性最低为 71.42 % ;单项 ECG电压标准特异性最高均为 10 0 % ,而敏感性最低为 1.2 8%～15 .38% ;ΣQRS振幅标准敏感性、特异性分别是 2 1.79%和 97.14% ;修改后计分标准分别是 38.46 %和 91.42 % ;而Fisher法标准分别是 43.5 9%和 88.5 7% ;结论

Objective:To study the accuracy of diagnosis of left ventricular hypertrophy with multiple ECG criterions.Method:Using a Colour Doppler Ultrasonic Echocardiograph as the reference,electrocardiograms of 113 patients with phase Ⅰ or phase Ⅱ primary hypertenson were observed, and multiple ECG criterions for the diagnosis of left ventricular hypertrophy were compared.Results:The highest sensitivity of the standard of New York Cardiodisease Association was 44.87% and the lowest specificity was 71.42%.The highest specificity of voltage of a single ECG criterion was 100%,and the lowest sensitivity was 1.28~15.38%.For criterion of ΣQRS,its sensitivity and specificity was 21.7% and 97.14%,respectively,and for a modified ΣQRS criteron,the specificity and sensitivity was 38.46% and 91.42%,respectivety.The specificity and sensitivity of the Fishers criterion,however,was 43.59% and 88.57% respectivdy.Conclusion:The multiple ECG criterions for diagnisis of left ventricalar hypertrophy do not show both high sensitivity and high specificity at the same time.
