BIORHYTHM CURVE MEASURING APPARATUS

摘要

PURPOSE:To noninvasively measure biorhythms on the basis of electrocardiographic data. CONSTITUTION:A circadian component extraction means 10 extracts components of circadian fluctuation from electrocardiographic data by calculating a value that represents a circadian component, from the time-series data for marginal time-series sections allotted to each unit hour, as a central value of the data level for each section. Next, a correction means 6 identifies the kinds of disturbances and determines their influences in time series on the basis of data on disturbance measurements and then the influences of the disturbances are eliminated by the method of eliminating and supplementing or correcting according to the identification result the data on the circadian components extracted from the electrocardiographic data.
