心脏功能的控制心脏的泵血工作由四项有关的主要血液动力学因子所调节(图1)。必需指出,收缩力仅是四项决定因子之一,心室工作亦可通过治疗,调整心排出量的其他三项主要决定因子而有所改善。心脏功能的决定因子 Cardiac function control Cardiac pumping work is regulated by four major hemodynamic factors (Figure 1). It must be pointed out that contractility is only one of the four determinants and that ventricular work can be improved by treating and adjusting for the other three main determinants of cardiac output. Determinants of cardiac function
