WebAug 24, 2024 · What causes the Dicrotic notch in a graph of aortic pressure? 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 truth awning hinge
