The purpose of this study was to evaluate the usefulness of two-dimensional echocardiographic (2D echo) measurements in diagnosing right ventricular hypertrophy (RVH). These measurements of the right atrium and the ventricle were made in 15 patients with right ventricular hypertrophy and in 11 normal subjects and were as follows: right atrium long axis 2.13 +/- 0.42 vs 1.36 +/- 0.11 cm/m2 (p less than 0.001); right atrium short axis 2.78 +/- 0.60 vs 2.06 +/- 0.26 cm/m2 (p less than 0.001); right atrial area 8.81 +/- 2.79 vs 4.00 +/- 0.33 cm2/m2 (p less than 0.001); right ventricular long axis 4.65 +/- 0.64 vs 3.27 +/- 0.49 cm/m2 (p less than 0.001); and right ventricular area 13.02 +/- 3.64 versus 6.19 +/- 0.74 cm2/m2 (p less than 0.001). The 2D echo right atrial area and long axis had a sensitivity and specificity of 100 percent in the diagnosis of right ventricular hypertrophy. We conclude that 2D echo is useful in the diagnosis of right ventricular hypertrophy.
本研究的目的是评估二维超声心动图（2D回声）测量在诊断右心室肥厚（RVH）中的有用性。对15例右心室肥厚患者和11名正常受试者进行了右心房和右心室的这些测量，结果如下：右心房长轴2.13±0.42 vs 1.36±0.11 cm/m2（p<0.001）；右心房短轴2.78±0.60 vs 2.06±0.26 cm/m2（p<0.001）；右心房面积8.81±2.79 vs 4.00±0.33 cm2/m2（p<0.001）；右心室长轴4.65±0.64 vs 3.27±0.49 cm/m2（p<0.001）；以及右心室面积13.02±3.64 vs 6.19±0.74 cm2/m2（p<0.001）。2D回声右心房面积和长轴在诊断右心室肥厚时的敏感性和特异性均为100%。我们得出结论，2D回声在诊断右心室肥厚方面是有用的。
