WebThe Frank-Starling connection states that when preload (end-diastolic pressure) rises, so does ventricular output. In summary, the Frank-Starling Law stipulates that the stroke volume of the left ventricle will increase as the left ventricular volume increases because the myocyte stretch causes a more forceful systolic contraction.
