Right bundle branch block was diagnosed in electrocardiograms of 37 of 1085 patients with essential hypertension. Echocardiographically left ventricular hypertrophy was diagnosed in 14 of these 37 patients. Eighteen electrocardiographic (ECG) criteria, which were previously recommended, were determined in these 37 patients. The sensitivities of five criteria were found to be better than 50%. These are SV1 > or = 2 mm; RV6 > RV5; S III + (R+S) maximum precordial lead > or = 30 mm; P/PR > or = 1.6; R aVL > or = 11 mm. However, their specificities ranged from 56.5% to 95.6%. When the combination of RV6 > RV5 and S III + (R+S) maximum precordial lead > or = 30 mm was used, sensitivity was 57.1 and specificity was 100%. It is concluded that the presence of right bundle branch block these ECG criteria can be used for the diagnosis of left ventricular hypertrophy.
在1085例原发性高血压患者中，有37例心电图诊断为右束支传导阻滞。在这37例患者中，超声心动图诊断为左心室肥厚的有14例。在这37例患者中确定了先前推荐的18项心电图（ECG）标准。发现五项标准的敏感性高于50%。这些标准是：SV1≥2mm；RV6＞RV5；SⅢ＋（R＋S）胸前导联最大值≥30mm；P/PR≥1.6；RaVL≥11mm。然而，它们的特异性范围为56.5%至95.6%。当使用RV6＞RV5和SⅢ＋（R＋S）胸前导联最大值≥30mm的组合时，敏感性为57.1，特异性为100%。结论是，这些心电图标准可用于诊断右束支传导阻滞患者的左心室肥厚。
