WebAug 8, 2024 · Dicrotic notch is usually seen one-third of the way down the descending limb of the pressure wave (Fig. 1 a). The secondary dicrotic wave occurs as the elastic recoil of the arterial tree clamps down against a closed aortic valve causing a … WebNext, closure of the aortic valve causes a notch known as the dicrotic notch (D). The dicrotic wave (DW) follows the dicrotic notch due to an echoed pulse from the lower body. The CP trace is affected by valvular faults such as mitral deficiency and aortic stenosis. CP is not generally utilized in clinical diagnosis and is acquired with ECG and ...
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. The summation of the reflected pulse ...
