WebThe dicrotic notch, or incisura, which interrupts the arterial downslope, represents the closure of the aortic valve, which occurs just moments after the start of diastole. At the end of diastole, the waveform reaches its nadir. Why is Phlebostatic axis important? WebThe dicrotic notch is a prominent and distinctive feature of the pressure waveform in the central arteries. It is universally used to demarcate the end of systole and the beginning of diastole in these arteries. Despite its importance clinically, no physical mechanism for the formation of the dicrotic notch has been demonstrated convincingly.
