Cardiac OutputComprehensionanalogyMinute of timeHeart Rate心排出量心率Cardiac output is the amount of blood the heart pumps in 1 minute, and it is dependent on the heart rate, contractility, preload, and afterload. Understanding of the applicability and practical relevance of each of these four ...
Oxygen delivery is primarily dependent on cardiac function and is therefore sensitive to changes in myocardial contractility, preload and afterload. However, matching oxygen delivery to metabolic activity requires circulatory adjustments and normal transfer kinetics. This article will discuss the regulation ...
The reduction in RV preload and the increase in RV afterload both lead to a decrease in RV SV, which is at a minimum at the end of the inspiratory period. The inspiratory reduction in RV ejection leads to a decrease in left ventricular filling after a phase lag of two or three ...
Nowadays the importance of RV has been recognized, and its role in the cardiac hemodynamics has been highlighted7,8. Actually, the circulatory system is a closed-loop where the function of both ventricles is crucial. Therefore, not infrequently, impairment of one of the two ventricles ...
