"WebFeb 3, 2024 · Diastolic Dysfunction. Ventricular filling in diastole relies on both a compliant ventricle and a pressure gradient between the left atrium and left ventricle (LV). In the early phase of diastole, active ventricular relaxation helps to generate this gradient by actively sucking blood into the ventricle via elastic recoil. " - Diastolic phase of ventricles
