Seven dimensions of the right ventricle at different levels and one dimension of the right auricle at the tricuspidal valve level were determined in 414 patients with cardiac ailments without volume loading. The data obtained are confronted with the hemodynamics of the right ventricle determined via clinical investigations, right cardiac catheterization and the method of dye dilution. A considerable correlation exists between the size of the EchoC-dimensions of the right ventricle and right auricle and the values of the final diastolic pressure in the right ventricle and the mean pressure in the right auricle, being a precondition for the determination of the right ventricle function via echocardiography. Enlargement of all EchoC-dimensions of the right ventricle and right auricle is present in right ventricle insufficiency. The echocardiography dimensions of the right ventricle and right auricle show a high sensitivity (91%) in the determination of initial right-ventricle insufficiency, presenting a relatively low false positive results (13%).
在414例无容量负荷的心脏病患者中，测定了不同水平右心室的七个维度以及三尖瓣水平右心耳的一个维度。将所获得的数据与通过临床检查、右心导管检查和染料稀释法测定的右心室血流动力学进行对比。右心室和右心耳的超声心动图维度大小与右心室舒张末期压力值及右心耳平均压力之间存在显著相关性，这是通过超声心动图测定右心室功能的前提条件。右心室功能不全时，右心室和右心耳的所有超声心动图维度均增大。右心室和右心耳的超声心动图维度在判定早期右心室功能不全方面显示出高敏感性（91%），假阳性结果相对较低（13%）。
