The extent (augmentation index, AIX%) and timing (reflected wave transit time, RWT, ms) of aortic wave reflection (measured using radial applanation pulse wave analysis, PWA, SphygmoCor device) were assessed on a single occasion in 114 consecutive RA patients without overt CV disease aged 40 65 years.
Although S1 did not demonstrate impaired brainstem processing relative to TD children at pre-training, response timing of Wave A became faster after training (improving from 1.5 SD above the TD mean to 0.25 SD above the TD mean.
While it was possible to demonstrate a clear difference in the timing of wave reflection between young, middle-aged, and elderly adult subjects, it is possible that the timing and magnitude of the reflected waves may differ in subjects even younger than those studied here.
Upon arrival at the detectors, the amplitude and timing of waves are recorded to give a seismogram (record of ground vibrations).
Comparing with the proper port-timing and wave arrangement, the loss due to gradual opening can significant effect the performance of WRR.
We present a case study of the relative timing of ULF wave onset across the Pi1 and Pi2 ULF wave bands.
The timing of the wave was measured using (i) the date on which the wave peaked (Tmax) and (ii) the midpoint in time of the wave (i.e., halfway between the start- (Tstart) and end-dates (Tend) of the wave, or ).
The uncertainty in the relative timing between ULF wave bands is defined as the summation of each individual ULF wave band uncertainty.
"The human ear-brain system is good at discerning changes in sound level," Choueiri explains, "but subtle changes in the relative timing between the wave components of a sound are too subliminal for humans to detect.
The magnitude, but not the timing of this wave is related to clinical factors.
