by RC Tarazi · 1982 · Cited by 108 — other criteria of afterload do depend in part on the performance of the heart. For example, the peak sys- tolic aortic pressure depends as much on ventricular.(15)

Preload and Afterload · Preload = “LV wall stress at end diastole”. Note that during diastole, the heart muscle is relaxed and the LVs are filling up with blood.(16)

6. Cardiac afterload – Osmosis

This leads us to a most commonly used definition of afterload, which says that afterload is the amount of resistance that the ventricles must overcome during (17)

In simple terms, the afterload is closely related to the aortic pressure. More precisely, afterload can be stated in terms of ventricular wall stress (s ), where s (P r) / x (18)
