FIELD: medicine.
SUBSTANCE: indices of heart rhythm variability are determined: normalised power in low frequency range, mode amplitude, maximal cardiointerval in sample. Values of coefficients F1 and F2 are calculated by formulas: F1=-13.46+35.1 × x1-8.04 × x2+7,48 × x3; F2=-12.17+27.97 × x1+4.41 × x2+7.76 × x3; where x1-LFnorm is normalised power in low frequency range; x2-AMo is mode amplitude (share of cardiointervals, corresponding to mode value); x3-max. is maximal cardiointerval in sample. Of F2 value is higher than F1, presence of intracranial hypertension of more than 20 mm Hg, and with F1 higher than F2, its absence is diagnosed.
EFFECT: method makes it possible to eliminated examination trauma and reduce diagnostics time.
