WebJun 12, 2024 · Contractility is the change in peak isometric force (isovolumic pressure) at a given initial fibre length (end diastolic volume). Its physiological determinants include preload, afterload (Anrep effect) and heart rate (Bowditch effect).

According to Starling’s Law, the heart will eject a greater stroke volume at greater filling pressures. For any filling pressure (LAP), the stroke volume will be greater if the contractility of the heart is greater.
