  • Title: [A visual diagnostic evaluation of the cerebral hemodynamics by rheo-encephalogram].
    Author: Sokolova IV.
    Journal: Med Tekh; 2004; (1):23-9. PubMed ID: 15080003.
    Abstract:
    A technology of a diagnostic evaluation of the cerebral-hemodynamic functional state made on the basis of rheoencephalogram end involving the two-component analysis method is described in the paper. The method consists in a quantitative representation of a qualitatively new regularity pertaining to the functioning of the cardiovascular system with a two-phase structure of cardiac output, i.e. the positive systolic one and the negative diastolic one, which is in line with the active functioning of the myocardium both in the systolic and diastolic cardiac-cycle phases. A partial separation of the arterial and venous components of rheoencephalogram, which reflect (during the cardiac cycle) the pulse fluctuations of voluminous blood filling in the arterial and venous sections of the examined bloodstream portion, is made use of. The method parameters provide for separate diagnostic evaluations of the tonus and blood filling of the arteries, veins and small peripheral vessels of the examined blood-stream portion. The computer-aided version of two-component analysis supports the rheoencephalogram processing in the sitting registration posture covering the full neurological examination range with respect to sex and age-related peculiarities of cerebral hemodynamics.
