测定了３９例少年游泳运动员右室负荷试验前后的心阻抗血流图。结果显示：当肺泡内压增高造成右室后负荷急性增加时，少年运动员的ＳＶ下降３１％，Ｃｏ下降１８％，ＳＴＩ亦发生明显的改变。文中对上述左心功能变化的机制作了初步探讨。
The heart impedance blood flow diagrams of 39 juvenile swimmers before and after right ventricular loading test were measured. The results showed that SV decreased by 31%, Co decreased by 18% and STI changed obviously when the increase of alveolar pressure resulted in an acute increase of right ventricular afterload. The article made a preliminary discussion on the mechanism of the left ventricular function changes.
