WebThis increases venous blood volume and CVP. This occurs when the heart is functioning normally. It is important to note, however, that arterial dilation in ventricular failure leads to a decrease in CVP instead of an increase. This occurs because the arterial dilation decreases afterload on the ventricle, leading to an increase in stroke volume.
