Surface electrocardiographic findings of 10 cases of left bundle branch block with echocardiographically determined left ventricular hypertrophy were compared with another 10 cases of left bundle branch block without left ventricular hypertrophy. Horizontal plane QRS- and T-wave angle > or = 150 degrees was highly sensitive (70%) and specific (90%) in diagnosing left ventricular hypertrophy in the presence of left bundle branch block. This diagnosis criterion was better than any other conventional criterion described before.
将10例经超声心动图测定有左心室肥厚的左束支传导阻滞患者的体表心电图表现，与另外10例无左心室肥厚的左束支传导阻滞患者进行比较。在存在左束支传导阻滞的情况下，水平面QRS波和T波角度≥150°对诊断左心室肥厚具有高度敏感性（70%）和特异性（90%）。该诊断标准优于之前描述的任何其他传统标准。
