报告的左心室（LV）尺寸和质量参考值的差异可能是由于早期超声心动图方法的成像错误或受试者特征和入选标准的影响。为了确定现代超声心动图方法是否为不同人群的左心室测量提供稳定的正常范围，对176名参加心脏强健研究的美国印第安人和237名临床正常的纽约市居民进行了M型/二维超声心动图检查。人群间左心室大小或功能的任何测量均无一致性差异。左室质量的正常上限（第98百分位数）女性为96 g/m2，男性为116 g/m2，左室腔直径（按身高标准化）为3.27 cm/m。因此，当代M型/2D超声心动图为LV测量提供了参考范围，该参考范围接近尸检测量值，并且在明显正常的白色、非洲裔美国人/加勒比海人和美洲印第安人人群中具有可接受的稳定性。
Discrepancies in reported reference values for left ventricular (LV) dimensions and mass may be due to imaging errors with early echocardiographic methods or effects of subject characteristics and inclusion criteria. To determine whether contemporary echocardiographic methods provide stable normal limits for left ventricular measurements in different populations, M-mode/2-dimensional echocardiography was applied in 176 American Indian participants in the Strong Heart Study and 237 New York City residents who were clinically normal. No consistent difference in any measure of LV size or function existed between populations. Upper normal limits (98th percentile) for LV mass were 96 g/m(2) in women and 116 g/m(2) in men and 3.27 cm/m for LV chamber diameter normalized for height. Thus contemporary M-mode/2D echocardiography provides reference ranges for LV measurements that approximate necropsy measurements and have acceptable stability in apparently normal white, African-American/Caribbean, and American Indian populations.
