Measurements of right ventricular wall thickness (RVWT) by echocardiography and at necropsy correlated well (r = 0.83) in 36 patients. Echocardiography had a sensitivity of 93% and a specificity of 95% in diagnosing right ventricular hypertrophy (RVH) at necropsy; electrocardiography (ECG) had a sensitivity of 31% and a specificity of 85% in diagnosing RVH. An additional 212 patients were studied by echocardiography and ECG. Based on echocardiographic criteria of RVH (RVWT Greater Than or Equal To 5 mm), 134 of 212 patients had RVH, and 78 were without RVH: the ECG had a sensitivity of 27% and a specificity of 88% for diagnosing RVH when correlated with the echocardiographic criteria. The mean diastolic RVWT was 6.0 +/- 1.4 mm in 134 RVH patients and 3.4 +/- 0.8 mm in 78 no-RVH patients (P Less Than 0.05). Diagnosis of RVH was difficult by ECG in 73 patients due to conduction defects or old myocardial infarction; the RVWT measurements were useful in evaluating RVH in these patients. We conclude that echocardiographic measurements of RVWT are useful in the diagnosis of RVH and are more sensitive than the ECG criteria in adults.
在36例患者中，通过超声心动图测量右心室壁厚度（RVWT）与尸检结果相关性良好（r = 0.83）。超声心动图在尸检时诊断右心室肥厚（RVH）的敏感性为93%，特异性为95%；心电图（ECG）诊断RVH的敏感性为31%，特异性为85%。另外212例患者接受了超声心动图和心电图检查。根据RVH的超声心动图标准（RVWT大于或等于5mm），212例患者中有134例患有RVH，78例没有RVH：与超声心动图标准相关时，心电图诊断RVH的敏感性为27%，特异性为88%。134例RVH患者的平均舒张期RVWT为6.0±1.4mm，78例无RVH患者为3.4±0.8mm（P<0.05）。73例患者因传导缺陷或陈旧性心肌梗死，心电图诊断RVH困难；RVWT测量有助于评估这些患者的RVH。我们得出结论，超声心动图测量RVWT对RVH的诊断有用，且在成人中比心电图标准更敏感。
