WebDicrotic notch occurs. Isovolumetric relaxation. Early diastole. The pumping action of the heart generates blood flow through the vessels along a pressure gradient, always moving from higher- to lower-pressure areas. What event recorded on the pulse channel corresponds to the Dicrotic notch what causes a Dicrotic notch? 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.

Broader applications of arterial pressure wave form analysis

The cardiac cycle involves four major stages of activity: 1) "Isovolumic relaxation", 2) Inflow, 3) "Isovolumic contraction", 4) "Ejection". (See Wiggers diagram, which presents the stages, label-wise, in 3,4,1,2 order, left-to-right.) Moving from the left along the Wiggers diagram shows the activities within four stages during a single cardiac cycle. (See the consecutive panels labeled, at bottom-right, "Diastole" then "Systole"). 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.
