WebJan 2, 2024 · The dicrotic limb begins during late systole as the flow of blood out of the left ventricle starts to decrease. The dicrotic notch marks the closure of the aortic valve and the beginning of diastole. The end diastole landmark is the location at which the patient’s actual diastolic blood pressure is measured. WebThe dicrotic notch (DN) is a negative wave that appears just after the peak systolic pressure, and the DN has been reported to reflect closure of the aortic valve and the …
