[The indices of central and peripheral hemodynamics and of autonomic nervous system function in subjects with arterial hypertension working under different manufacturing conditions]. / Pokazateli tsentral'noi i perifericheskoi gemodinamiki, sostoianiia vegetativnoi nervnoi sistemy u lits s arterial'noi gipertenziei, rabotaiushchikh v razlichnykh proizvodstvennykh usloviiakh.

As many as 318 persons with arterial hypertension working at an industrial enterprise, engaged in agricultural production, and in the sphere of mental work, were examined. The control group consisted of 40 essentially healthy subjects from the above cohorts. The following subgroups were identified in the groups observed: borderline arterial hypertension, I and II stage hypertensive disease. The examination involved electrocardiography, tetrapolar rheography, echocardiography, rheoencephalography, phonotacho-oscillography, variation pulsography, orthostatic test. Several distinguishing features were noted of central and peripheral hemodynamics, state of the vegetative nervous system in different occupational groups, which fact allows adoption of optimal, pathogenetically substantiated therapy of arterial hypertension in the cohorts followed-up.

[Use of phonotacho-oscillography in the diagnosis of neurocirculatory dystonia and hypertension]. / Primenenie fonotakhoostsillografii v diagnostike neirotsirkuliatornoi distonii i gipertonicheskoi bolezni.

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.
