Both are under the control of the sympathetic nervous system. Stroke volume is also affected by changes in preload, contractility and afterload, and their interaction. This chapter will deal with preload and afterload only. For the effect of contractility on cardiac performance, see chapter Cardiac cycle: pressure–volume relationships. Venous return (preload) depends on blood volume, posture and venous tone. Venous tone is under the control of the sympathetic nervous system. Sympathetic output changes in response to the peripheral metabolic need.Read More
