Abstract
1. Способ определения изменения функционального состояния человека, заключающийся в том, что из электрокардиосигнала выделяют позиции R-зубцов и строят одномерный ряд RR-интервалов, на основе полученного ряда формируют функцию накопления в виде одномерного кумулятивного ряда, которую пошагово разбивают на фрагменты и для каждого фрагмента определяют функцию тренда, которую затем вычитают из значений, входящих в этот фрагмент, отличающийся тем, что для вновь полученных значений фрагмента вычисляют среднеквадратическое отклонение, по полученным значениям составляют массив элементов, который преобразуют в прямоугольную матрицу и для каждого столбца прямоугольной матрицы строят кривую зависимости среднеквадратического отклонения от масштаба, для полученной кривой находят функцию линейной аппроксимации, по наклону которой определяют масштабный показатель сигнала, после чего стоят график зависимости мгновенного значения масштабного показателя от номера столбца. ! 2. Устройство для реализации способа определения изменения функционального состояния человека, содержащее последовательно соединенные блок первичной обработки сигнала, вход которого является входом устройства, блок формирования RR-интервалов, блок формирования функции накопления, блок фрагментирования, блок удаления тренда, выход которого является выходом устройства, отличающееся тем, что в него введены последовательно соединенные блок вычисления среднеквадратического отклонения, вход которого соединен с выходом блока удаления тренда, а выход блока вычисления среднеквадратического отклонения подключен к входу блока интерполяции, вы� 1. A method for determining changes in the functional state of a person, consisting in the fact that the positions of R-teeth are extracted from the electrocardiogram and a one-dimensional series of RR-intervals is built, on the basis of the obtained series, the accumulation function is formed in the form of a one-dimensional cumulative series, which are stepwise divided into fragments and for each of the fragment determines the trend function, which is then subtracted from the values included in this fragment, characterized in that for the newly obtained values of the fragment, the standard deviation is calculated by gender the scientific values are an array of elements that are converted into a rectangular matrix and for each column of the rectangular matrix a curve of the standard deviation of the scale is plotted for the obtained curve, a linear approximation function is found, the slope of which is used to determine the signal scale, and then there is a graph of the dependence of the instantaneous value of the scale indicator from the column number. ! 2. A device for implementing a method for determining a change in the functional state of a person, comprising a series-connected unit for primary signal processing, the input of which is the input of the device, a unit for generating RR intervals, a unit for generating an accumulation function, a fragmentation unit, a trend removal unit, the output of which is the output of the device, characterized in that a series-connected mean-square deviation calculation unit is introduced into it, the input of which is connected to the output of the deletion unit yes, and the output of the standard deviation calculating section connected to the input of interpolation unit, you
