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. WebThe dicrotic notch is not related to electrical activity and is therefore not seen on the ECG. The dicrotic notch is an indentation or "dip" in the graph of aortic pressure over time during...

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. 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.
