Specifically, they note that the usual anacrotic and dicrotic notches were absent from the pulse waves of their people with aortic stenosis.
2.
When pressure within the ventricles drops below pressure in both the pulmonary trunk and aorta, blood flows back toward the heart, producing the dicrotic notch ( small dip ) seen in blood pressure tracings.
3.
The graph of aortic pressure throughout the cardiac cycle displays a small dip ( the " incisure " or " "'dicrotic notch "'" ) which coincides with the aortic valve closure.
