1 Definition

End diastolic volume (EDV) is the amount of blood that is in a ventricle of the heart at the end of diastole. The EDV for an average adult male at rest is usually about 120 ml.

2 Physiology

The value of the end diastolic volume depends on the duration of the ventricular diastole as well as on the venous pressure. Increases in either of the these values raises the EDV. A slow heart rate means a longer diastole and more time for blood to fill the ventricles. Exercise increases the venous pressure by raising the speed of venous return (since the heart rate is higher and the active skeletal muscles press on veins returning blood to the heart).

Decreases in the duration of ventricular diastole (e.g. during extremely rapid heart rate) or a low venous pressure (e.g. as a result of severe blood loss) lower the end diastolic volume.
