[Use of phonotacho-oscillography in the diagnosis of neurocirculatory dystonia and hypertension].
A total of 95 persons were screened for the most informative phonotacho-oscillographic (PTOG) signs to differentiate between neurocirculatory dystonia and essential hypertension. They included 45 patients with stages I and II of essential hypertension, 22 patients with neurocirculatory dystonia and 28 healthy subjects (the control group). A new index alpha is offered, which represents the ratio of the products AM . Ti/Ai . Tm, where Ai is the amplitude of the initial portion, Am - the amplitude of the middle portion, Ti - the duration of the initial and Tm - the duration of the middle portion of the PTOG complex at the level of the maximum arterial pressure. The index alpha in healthy persons was 0.58 +/- 0.04; in the patients with neurocirculatory dystonia 1.02 +/- 0.06, and in the patients with essential hypertension 4.25 +/- 0.26. This index is offered for differential diagnosis between neurocirculatory dystonia and essential hypertension, especially during the functional test with nitroglycerin.
