dicrotic การใช้

• Conditions associated with low cardiac output and high systemic vascular resistance can produce a dicrotic pulse.
• The dip in the graph is immediately followed by a brief rise ( the " dicrotic wave " ) then gradual decline.
• Specifically, they note that the usual anacrotic and dicrotic notches were absent from the pulse waves of their people with aortic stenosis.
• Moreover, conditions associated with low systemic vascular resistance and a compliant aorta ( e . g . sepsis ) can also produce a dicrotic pulse, although the mechanism is not entirely understood.
• 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.
• 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.
