WebThe change in the pressure gradient forces the aortic valve to close. The combination of elastic recoil of the aorta and blood rebounding against the valve causes a rebound of aortic pressure called the dicrotic notch. The AV valve also remains closed because the ventricular pressure is still higher than atrial pressure. Webin it expands. At the beginning of diastole, the aorta begins to recoil pushing blood forward to the systemic circulation but also back toward the ventricle. The sudden closing of the aortic valve produces a pressure wave as the blood pushes against it, resulting in the observed spike in aortic pressure. This spike is called the dicrotic notch. fnf poppy playtime chapter 2 bunzo mod

WebAt the beginning of diastole, the aorta begins to recoil pushing blood forward to the systemic circulation but also back toward the ventricle. The sudden closing of the aortic valve produces a pressure wave as the blood pushes against it, resulting in the observed spike in aortic pressure. This spike is called the dicrotic notch. The cardiac cycle involves four major stages of activity: 1) "Isovolumic relaxation", 2) Inflow, 3) "Isovolumic contraction", 4) "Ejection". (See Wiggers diagram, which presents the stages, label-wise, in 3,4,1,2 order, left-to-right.) Moving from the left along the Wiggers diagram shows the activities within four stages during a single cardiac cycle. (See the consecutive panels labeled, at bottom-right, "Diastole" then "Systole").
