在112例成人患者中，将标准12导联心电图（ecg）的QRS振幅、持续时间和平均电轴方向与左心室质量、容积、室壁厚度和每搏作功进行比较。这些患者左心室正常或有不同程度的左心室扩张或肥厚。通过定量心血管造影方法测定左心室容积和质量。左心室质量与心电图电压之间存在显著但不密切的相关性，舒张末期容积、每搏输出量、每搏作功、室壁厚度和“左心室总容积”（左心室肌容积和左心室末腔容积）与QRS振幅的相关程度通常低于单独的质量。将患者分组为左心室压力超负荷、容量超负荷、主动脉瓣疾病或解剖左心室肥大并不能改善相关性。Sokolow和Grant的左心室肥厚电压标准进行了评估：分别为68%和67%的75例解剖性肥厚患者有高电压。左心室解剖长轴方向与平均QRS向量方向无显著相关性。
The QRS amplitude, duration, and mean axis direction of the standard 12-lead electrocardiogram [ecg] were compared with left ventricular mass, volume, wall thickness, and stroke work in 112 adult patients. These patients had normal left ventricles or various degrees of left ventricular dilation or hypertrophy. Left ventricular volumes and mass were determined by a quantitative angiocardiographic method. A significant but not a close correlation between left ventricular mass and ecg voltage was found. End-diastolic volume, stroke volume, stroke work, wall thickness, and "total left ventricular volume" (volume of left ventricular muscle and cavity at end-diastole) had generally lesser degrees of correlation with the QRS amplitude than did the mass alone. Subgrouping of patients into those with pressure overload on the left ventricle, volume overload, aortic valve disease, or anatomic left ventricular hypertrophy did not improve correlations. The left ventricular hypertrophy voltage criteria of Sokolow and of Grant were assessed: respectively, 68% and 67% of 75 patients with anatomic hypertrophy had hypervoltage. The direction of the anatomic long axis of the left ventricle was not significantly related to the mean QRS-vector direction.
