The first Gaussian function [f.sub.1](n) denotes the main wave, or the forward wave; the second Gaussian function [f.sub.2](n) denotes the tidal wave; and the third Gaussian function [f.sub.3](n) denotes the dicrotic
wave, or the backward wave.
The results of the current study showed that Allo has alleviated the vascular complications of IR including systolic, diastolic, mean, and dicrotic
notch pressures compared to the untreated IR group.
Tone characteristics of cerebral vessels and parameters of blood supply were found to have similar relationship; the longer drug use duration is the less blood supply of cerebral vessels as well as lower dicrotic
index characterizing vascular tone can be observed.
Note: Healthy CV patients have a well defined "dicrotic
wave" in the diastolic phase at D, whereas 98% of overt arteriosclerotic patients had significant decrease or disappearance of the wave.
The tongue is furred, the pulse is full and bounding, but rarely dicrotic
. The temperature may range from 102 to 103[degrees]F, or is in some instances higher.
When blood begins to flow across the aortic valve, a dicrotic
notch appears on the arterial wave form.
Normal individual ICP pulse waveforms (Fig 1) generally have three characteristic peaks of decreasing height that correlate with the arterial pulse waveform and are referred to as P1 (percussion wave), P2 (tidal wave), and P3 (dicrotic
wave). P1 generally has a sharp peak and a fairly constant amplitude.
1, the pressure range was limited to maintain the presence of an apparent dicrotic
notch in the waveform derivative whose disappearance has been observed to precede the shutdown of pulsing blood vessels.
Because the forward and reflected waves of ABP waveforms are separated by the dicrotic
notch, there are two expected harmonic peaks that should exist when ABP waveforms are analyzed using Fourier analysis.
