Dicrotic notch cause

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 ...

Differences between the arterial pulse pressure wave and tissue flow wave are discussed, as well as the cause of certain artifacts, including the wandering dicrotic notch.

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").
