Answer:
Increase EDV and therefore, increase stroke volume.
Explanation:
EDV is the volume of blood which filled the ventricle before its contraction while ESV is the volume of blood remain in ventricle after ejection.
When venous return increases, this will increase the pressure on ventricle contraction which can lead to eject of addition blood returned to it.
So, increase in EDV results in an increase of stroke volume (SV).
