WebThe closure of the aortic valve causes a rapid change in pressure in the aorta called the incisura. This short sharp change in pressure is rapidly attenuated down the arterial tree. The pulse wave form is also reflected from branches in the arterial tree and gives rise to a dicrotic notch in main arteries.

What is the Dicrotic notch and why does it happen?
WebThe dicrotic notch is a prominent and distinctive feature of the pressure waveform in the central arteries. It is universally used to demarcate the end of systole and the beginning of diastole in these arteries. Despite its importance clinically, no physical mechanism for the formation of the dicrotic notch has been demonstrated convincingly. WebDicrotic notch/incisura pressure drop followed by small pressure increase as a result of valve recoiling 5. Aorta settles, heart relaxes → pressure drops 138 OSMOSIS.ORG Pulse pressure lower in aorta than in large arteries → because pressure from blood travels faster than blood itself; pressure waves bounce off branch points in arteries ...
