Echocardiograms were obtained on 27 adults with electrocardiographic criteria of left ventricular hypertrophy (LVH) to determine how echocardiograms might best identify LVH. Both the left ventricular (LV) posterior wall thickness and interventricular septal thickness were found by echocardiography to be increased (greater than or equal to 12 mm) in only 13 of 27 patients (48%) with LVH. The LV was dilated (greater than or equal to 58 mm) in the absence of posterior wall thickening in 9 of 27 patients (33%). The LV mass, estimated from standardly measured dimensions, was increased (greater than 200 g) in 21 of 27 patients (78%) and when measurements were made by the Penn method, mas was increased in all patients. These observations indicate that the echocardiographic estimation of LV mass is a more sensitive indicator of LVH than LV posterior wall and septal thickness. Since LVH is defined as an increased mass of LV muscle, these observations are consistent with this fundamental definition of left ventricular hypertrophy.
对27名符合左心室肥厚（LVH）心电图标准的成年人进行了超声心动图检查，以确定超声心动图如何能最好地识别LVH。通过超声心动图发现，在27例LVH患者中，只有13例（48%）的左心室（LV）后壁厚度和室间隔厚度增加（大于或等于12毫米）。27例患者中有9例（33%）在没有后壁增厚的情况下LV扩张（大于或等于58毫米）。根据标准测量尺寸估计的LV质量，在27例患者中有21例（78%）增加（大于200克），当采用宾夕法尼亚方法进行测量时，所有患者的质量均增加。这些观察结果表明，与LV后壁和室间隔厚度相比，超声心动图对LV质量的估计是LVH更敏感的指标。由于LVH被定义为LV肌肉质量增加，这些观察结果与左心室肥厚的这一基本定义一致。
