Normal M-mode echocardiography values were determined using computer-assisted measurements of echocardiograms (ECHO) in 202 children and young adults 25 days to 23 years of age: 77 were female, and 125 were male and, reflecting the population served by our Center, 99 were black and 103 were white children. The values for left and right heart wall thicknesses and chamber sizes were graphically displayed as a function of body surface area, and with an illustration of the regression line and 2 standard deviation (SD) range of normal for each parameter. In addition, normal ECHO predicting equations for dimension and function parameters were derived using multiple linear regression analysis with age, height, weight, sex, race, and heart rate as independent variables. A comparison was made between the observed data and the data derived from the normal predicting equations for each of the parameters. Also, values obtained from these equations were compared to data generated from other published normal predicting equations. A description of the digitizer measurements, computer interfacing, and a sample ECHO report form utilizing the predicted normal ranges for each of the parameters is presented. We propose that quantitative M-mode echocardiographic reporting should be easily accessible to all pediatric cardiology laboratories.
通过计算机辅助测量202名年龄在25天至23岁的儿童和年轻人的超声心动图（ECHO），确定了正常M型超声心动图值：其中77名是女性，125名是男性，并且反映了我们中心服务的人群，99名是黑人儿童，103名是白人儿童。左、右心壁厚度和腔室大小的值以体表面积的函数形式图形显示，并给出了回归线以及每个参数正常范围的2个标准差（SD）。此外，使用年龄、身高、体重、性别、种族和心率作为自变量进行多元线性回归分析，得出了维度和功能参数的正常ECHO预测方程。对每个参数的观察数据与从正常预测方程得出的数据进行了比较。还将从这些方程获得的值与其他已发表的正常预测方程生成的数据进行了比较。介绍了数字化测量、计算机接口以及使用每个参数预测正常范围的ECHO报告样本形式。我们建议所有儿科心脏病学实验室都应能够轻松获取定量M型超声心动图报告。
