Abstract

FIELD: medicine. SUBSTANCE: method involves evaluating sympathico- parasympathic balance index (SPBI) value from R-R interval distribution as ratio of two parameters: mode amplitude and the number of positions (N) forming the distribution. Logarithmic scale is used. R-R interval estimate resolution capacity is defined to be equal to 0.01 s. Positive value and magnitude of the SPBI determine domination and domination measure of sympathic component of organism cardiovascular system, respectively. Negative value and magnitude of the sympathico-parasympathic balance index determine domination and domination measure of parasympathic component of organism cardiovascular system, respectively. R-R interval distribution median frequency (F, Hz) is evaluated. A patient is identified with respect to his individually typological cardiovascular activity specific features by means of two-dimensional plane vector coordinates, where SPBI is the ordinate (conditional units, logarithmic scale), and apex is the R-R interval distribution median frequency (Hz) in (100x5) cardiocycles. Cardiovascular system activity types of an organism are set in correspondence to different human attention shiftability levels. EFFECT: unbiased evaluation of human attention properties.

Использование: медицина, психофизиология, кардиология. Задача изобретения: объективизация способа оценки уровня переключаемости внимания человека в связи с оценкой индивидуально-типологических особенностей сердечно-сосудистой активности организма. В способе оценивают индекс симпатико-парасимпатического баланса по распределению R-R-интервалов как отношение двух параметров: амплитуды моды (Ам) и количества разрядов, входящих в распределение (N). Используется логарифмический масштаб. Предусматривается разрешающая способность оценки R-R-интервалов 0,01 с. Положительное значение и величина индекса симпатико-парасимпатического баланса (ИСПБ) определяют преобладание и меру преобладания соответственно симпатической составляющей сердечно-сосудистой системы организма. Отрицательное значение и величина ИСПБ указывают на преобладание и меру преобладания соответственно парасимпатической составляющей системы организма. Оценивают частоту медианы распределения R-R-интервалов (Fме, Гц). Пациент идентифицируется в отношении индивидуально-типологических особенностей сердечно-сосудистой активности координатами вектора на двухмерной плоскости, где ординатой является ИСПБ (усл.ед., логарифмический масштаб), а абсциссой - частота медианы R-R-распределения (Гц) в (100х5) кардиоциклах. Типам сердечно-сосудистой активности организма поставлены в соответствие различные уровни переключаемости внимания человека.Usage: medicine, psychophysiology, cardiology. The objective of the invention: objectification of the method for assessing the level of switching attention of a person in connection with the assessment of the individual typological features of the cardiovascular activity of the body. In the method, the sympathetic-parasympathetic balance index is evaluated by the distribution of R-R intervals as the ratio of two parameters: mode amplitude (Am) and the number of discharges included in the distribution (N). The logarithmic scale is used. Resolution resolution of R-R intervals of 0.01 s is provided. The positive value and magnitude of the sympathetic-parasympathetic balance index (ISPB) determine the predominance and measure of predominance, respectively, of the sympathetic component of the cardiovascular system of the body. The negative value and magnitude of ISPB indicate the predominance and measure of predominance, respectively, of the parasympathetic component of the body system. Estimate the frequency of the median distribution of the R-R intervals (Fme, Hz). The patient is identified with respect to the individual typological features of cardiovascular activity by the coordinates of the vector on a two-dimensional plane, where the ordinate is ISPB (conventional unit, logarithmic scale), and the abscissa is the frequency of the median R-R distribution (Hz) in (100x5) cardiocycles. The types of cardiovascular activity of the body are associated with different levels of switching attention of a person.
