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. WebWhen pressure within the ventricles drops below pressure in both the pulmonary trunk and aorta, blood flows back toward the heart, producing the dicrotic notch (small dip) seen in blood pressure tracings. The …

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.

As both flow and pressure are strongly coupled, this momentary backflow would produce a small positive shift in the aortic pressure trace. The dicrotic notch would therefore be the result of a short period of backward flow of blood immediately before the aortic valve closes.Mar 15, 2016
