Passive ventricular filling

WebJul 7, 2024 · LV filling occurs during diastole, which has 4 phases: (1) isovolumic relaxation; (2) rapid filling phase; (3) slow filling, or diastasis; and (4) final filling during atrial systole (atrial kick.) Isovolumic relaxation – this phase occurs after the aortic valve closes and the mitral valve is still closed. WebNov 11, 2024 · In the diastole phase, heart ventricles relax and the heart fills with blood. In the systole phase, the ventricles contract and pump blood out of the heart to arteries. One cardiac cycle is completed when the heart …
