The feasibility of subxiphoid echocardiography to measure the thickness of the right ventricular wall (RVWT) was investigated. In 87 (90.6%) of the 96 patients studied, adequate visualization of the echoes from the right ventricular wall was obtained using the subxiphoid technique. RVWT averaged 0.34 +/- 0.08 cm (mean +/- 1 SD), ranging from 0.2 to 0.5 cm in 25 normal individuals. This was not significantly different from the values in the left ventricular overload group (0.36 +/- 0.10 cm). However, the RVWT was increased significantly (P less than 0.001) in the combined group (0.62 0.18 cm), the right ventricular (RV) pressure overload group (0.60 +/- 0.13 cm) and the RV volume overload group (0.53 +/- 0.11 cm). Thirty-two patients underwent diagnosis right heart catheterization which revealed a good correlation between the RVWT measured echocardiographically and the right ventricular peak systolic pressure (r = 0.84). Subxiphoid echocardiography was considered to be useful in diagnosing right ventricular hypertrophy in adults.
研究了剑突下超声心动图测量右心室壁厚度（RVWT）的可行性。在96例研究患者中，87例（90.6%）采用剑突下技术获得了右心室壁回声的充分可视化。25名正常个体的RVWT平均为0.34±0.08cm（均值±1标准差），范围为0.2至0.5cm。这与左心室超负荷组的值（0.36±0.10cm）无显著差异。然而，在联合组（0.62±0.18cm）、右心室（RV）压力超负荷组（0.60±0.13cm）和RV容量超负荷组（0.53±0.11cm）中，RVWT显著增加（P<0.001）。32例患者接受了右心导管诊断，结果显示超声心动图测量的RVWT与右心室收缩压峰值之间具有良好的相关性（r=0.84）。剑突下超声心动图被认为对诊断成人右心室肥厚有用。
