Four commonly used sets of electrocardiographic (ECG) criteria for diagnosing right ventricular hypertrophy (RVH) were tested for sensitivity and specificity in 12 men with isolated RVH, 15 with combined right and left ventricular hypertrophy and 24 with normal ventricular weights. The cardiac ventricles were weighed separately at autopsy and the left-to-right ratio was calculated. All the patients showing isolated RVH, with a left-to-right ratio of two or less, had died of respiratory causes. Three sets of ECG criteria showed a specificity of 100 percent, but sensitivities only from 26 to 44 percent. One set was more sensitive (74 percent) but much less specific than the others (79 percent). A new combination of ECG criteria attained a 63 percent sensitivity and a 96 percent specificity.
对诊断右心室肥厚（RVH）常用的四套心电图（ECG）标准进行了测试，以评估其在12例单纯性RVH男性、15例合并左右心室肥厚男性以及24例心室重量正常男性中的敏感性和特异性。在尸检时分别称量心脏各心室重量，并计算左右心室重量比。所有单纯性RVH患者，其左右心室重量比为2或更低，均死于呼吸相关原因。三套ECG标准显示特异性为100%，但敏感性仅为26%至44%。一套标准更敏感（74%），但特异性远低于其他标准（79%）。一套新的ECG标准组合达到了63%的敏感性和96%的特异性。
