Right ventricular (RV) wall thickness was measured from M-mode echocardiograms at end-diastole from both the parasternal and subcostal approaches in 50 children of various body surface areas (0.24 to 1.68 m2). The measurements were obtained from M-mode recordings generated from sector scans to ensure precise location and position. Twenty-three children had normal hearts, and 27 had various congenital heart defects that may be associated with RV hypertrophy. Corresponding measurements of the RV wall thickness at end-diastole from the 2 approaches were similar. Subcostal echocardiographic measurement of RV wall thickness was found to be a reliable alternative to parasternal measurement in children with normal hearts and in those with congenital heart disease and RV hypertrophy.
在50名不同体表面积（0.24至1.68平方米）的儿童中，通过胸骨旁和肋下途径，从舒张末期的M型超声心动图测量右心室（RV）壁厚度。测量值取自扇形扫描产生的M型记录，以确保精确的位置和定位。23名儿童心脏正常，27名患有各种可能与右心室肥厚相关的先天性心脏缺陷。两种途径在舒张末期测得的右心室壁厚度的相应测量值相似。对于心脏正常的儿童以及患有先天性心脏病和右心室肥厚的儿童，发现肋下超声心动图测量右心室壁厚度是胸骨旁测量的可靠替代方法。
