WebJan 1, 2024 · The dicrotic notch is formed by the reflection of a wave off of the aortic valve, following valve closure (Lewis, 1906). Thus, it is clearest in proximal pressure signals … WebThe bulge is referred to as the dicrotic notch. This signifies the closure of the aortic valve at the end of systole. The peaks average the systolic pressure. The troughs average the diastolic pressure. With an arterial waveform, note the scale range. Systolic and diastolic blood pressure ranges should fit within the scale of the waveform.
