WebWhat is the dicrotic notch? Why does it follow the T wave? The dicrotic notch is a short-lived decrease in pressure in the aorta following the closure of the aortic valve. Blood just pumped out of the left ventricle temporarily flows back against the closed aortic valve, leading to a v shaped notch in the pulse pressure wave WebWhat does dicrotic notch represent With the greater pressure in the aorta than in the left ventricle, blood flow attempts to equalise by flowing backwards, this causes the aortic valve to close. On the waveform, aortic valve closure is seen as the dicrotic notch. This event marks the end of systole and the onset of diastole (end of T wave on ECG). the slipway restaurant thomaston maine
