cardiac stroke volume的意思|示意

Objective: To evaluate the accuracy of two-dimensional and three-dimensional (3d) color Doppler echocardiography in cardiac stroke volume quantification.

目的：比较二维超声及三维彩色多普勒超声在心搏出量计算方面的准确性。

Increases Cardiac Output, stronger heart contractions pump more blood, increased stroke volume, thickens left ventricle wall (more muscular), decreases hearts' oxygen requirements.

心输出量增加，心脏收缩加强能泵更多的血液，心搏量增加，左心室壁变厚(更多肌肉)，心脏对氧气的需要减少。

Endurance training results in an increase in oxygen consumption and delivery. Stroke volume and cardiac output increase. Peripheral vascular resistance decreases.

耐力训练导致耗氧量和清除量增加，心脏搏出量和输出量增加，外周血管阻力下降。
