236 children of all age-groups, without any evidence of cardiopulmonary disease, underwent measurement of the diameters of the right pulmonary artery (RPA) in the suprasternal M-mode echocardiogram with respect to the characteristic motion pattern of the RPA. Since a high correlation was found between these diameters and height (r = 0.94; y = 1.66 square root X - 6.19), the children were divided into 9 sub-groups according to height, and mean values were calculated for all parameters in each sub-group. The systolic expansion of the RPA ranged from 18% to 30% within groups and correlated only weakly to height (r = 0.28). Suprasternal echocardiographic standards for measurement of the RPA may enhance the usefulness of this echocardiographic approach in pediatrics.
236名各年龄组儿童，无任何心肺疾病证据，在胸骨上M型超声心动图中，根据右肺动脉（RPA）的特征性运动模式测量RPA直径。由于发现这些直径与身高之间存在高度相关性（r = 0.94；y = 1.66√X - 6.19），根据身高将儿童分为9个亚组，并计算每个亚组所有参数的平均值。RPA的收缩期扩张在组内范围为18%至30%，与身高的相关性较弱（r = 0.28）。胸骨上超声心动图测量RPA的标准可能会提高这种超声心动图方法在儿科中的实用性。
