Dicrotic notch arterial line
WebWhat does dicrotic notch represent With the greater pressure in the aorta than in the left ventricle, blood flow attempts to equalise by flowing backwards, this causes the aortic … WebMar 19, 2024 · The arterial waveform will show a notch on the downward stroke; this notch is called the dicrotic notch and is due to the closure of the aortic valve. The remainder of the downward stroke is the diastolic flow of blood into the arterial tree. A patient with abnormal heart rhythm or valvular abnormalities will have an abnormal arterial waveform.

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.
