unique frequency at the end of the program - but as we
do not have any tests showing the effect of the same
tape without this frequency at the end (it might f.ex. be
substituted by 43 Hz, which is one octave below 86 Hz),
this must remain to be only an assumption.
There is more substance to the observation that most of
the tapes are single (or double) frequency tapes in the
40 - 44 Hz area. The 57 Hz tape has a significant effect
on Pulse only. It may therefore be correct to state that
frequencies in the 40 Hz area, combined with music
specially composed for relaxation, have the most
predictable effect on lowering BP values in the patients.
EFFECT OF VAT ON PATIENTS WITH
ELEVATED AND LOWERED BLOOD PRESSURE
It may be of interest to have a closer look on the effect of
VAT on patients with elevated (DBP > 90 mm Hg) and
low (DBP < 65 mm Hg) Blood Pressure.
638
We here can see a significant difference in DBP
variations which can be observed in the two groups of
patients. The variance in SBP is of no significance. This
observation supports the Estonian observations that
VAT may be used to treat elevated Blood Pressure.
