This was associated with increased end-diastolic pressures during handgrip exercise and with decreased stroke volume and a leftward shift of pressure-volume loops during atrial pacing.

这与在握力试验中增加舒张末期压力和在心房起搏时减少猝发容量和左转向压力容积环路相关联。

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。

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。

Experiments were performed in perfused beating rabbit's right atria using radioimmunoassay to determine the effects of CNP on the stroke volume, pressure and atrial natriuretic peptide(ANP)secretion.

采用兔离体搏动右心房灌流模型和放射免疫分析方法，观察CNP对右心房每搏输出量、每搏压和心房钠尿肽（ANP）分泌的效应；
