A total of 120 healthy infants, children, and teenagers were examined by cross-sectional echocardiography. Right and left atrial and ventricular dimensions and areas were measured in the parasternal, apical, and subcostal views. Dimensions of the inferior caval vein, the pulmonary artery and the aorta were obtained in the parasternal, suprasternal, and subcostal views. Reproducibility was studied in separate material consisting of 19 children with various forms of congenital heart disease examined consecutively by two different observers. Interobserver reproducibility was expressed as the 95% tolerance limit for the difference between two measurements. Good correlation with body surface area was demonstrated for all measurements, and the regression equations for the normal values of the parameters studied are given. Interobserver reproducibility was fairly good for measurements in the parasternal views, but moderate or low for measurements in the apical and the subcostal four-chamber views. Measurements in cross-sectional echocardiography are clinically useful, especially in the study of the right-sided cardiac structures that are difficult to evaluate with M-mode echocardiography, but the problems of reproducibility have to be taken into account.
共有120名健康婴儿、儿童和青少年接受了横断面超声心动图检查。在胸骨旁、心尖和肋下视图中测量右心房、左心房以及右心室和左心室的尺寸和面积。在胸骨旁、胸骨上和肋下视图中获取下腔静脉、肺动脉和主动脉的尺寸。在由19名患有各种先天性心脏病的儿童组成的单独材料中研究了可重复性，这19名儿童由两名不同的观察者连续进行检查。观察者间的可重复性表示为两次测量之间差异的95%容忍限度。所有测量结果均显示与体表面积具有良好的相关性，并给出了所研究参数正常值的回归方程。观察者间在胸骨旁视图测量中的可重复性相当好，但在心尖和肋下四腔视图测量中的可重复性中等或较低。横断面超声心动图测量在临床上是有用的，特别是在研究难以用M型超声心动图评估的右侧心脏结构时，但必须考虑到可重复性问题。
