Frank-Starling mechanism
an intrinsic adaptive response which serves to adjust each ventricular output to its inflow by increasing the force of contraction of the myocardium proportionally to any increase in the length of the muscle fibers.

Through rhythmic pumping of the great veins, blood is returned to the heart and improves cardiac output via the Frank-Starling mechanism.
This phenomenon is called the Frank-Starling mechanism and together with the greater volume of blood to be pumped, it helps to make up for the lower heart rate.
But there's at least one other pathway, the Frank-Starling mechanism, that can increase the force of these contractions.
