[Integral assessment of cerebral hemodynamics normally, at a borderline level of arterial pressure and in arterial hypertension].

Cerebral circulation in relation to central hemodynamics was examined by means of rheoencephalography and chest rheography in 667 individuals with normal and elevated arterial blood pressure. Cardio-cerebral mechanisms are shown to be pathogenetically engaged since early stages of arterial hypertension. They are manifested as decreased cerebral stroke volume, smaller pulse inflow to cerebral arteries and increased vascular tonicity. Cerebral circulatory disorders grew more severe as the disease progressed.
