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. WebWith late inflation, the balloon inflates after the aortic valve closes. The dicrotic notch precedes the inflation point, and the notch and the inflation point create a W shape. This …

The Dicrotic Arterial Pulse Circulation

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").
