摘要

PROBLEM TO BE SOLVED: To quantitively evaluate the disturbance degree of a biometric rhythm.SOLUTION: The disturbance degree calculation device for a biometric rhythm has: a physiological parameter time-series data acquisition unit for acquiring physiological parameter time-series data calculated on the basis of the biometric signal of a subject; a calculation period determination unit for determining a calculation period, which is to be a length of time of roughly one-half of a period over which normal physiological parameter time-series data which have been calculated on the basis of the normal biometric signal vary; a calculation unit for calculating, for the calculation period, the shift amount between phases of inspection-time physiological parameter time-series data calculated on the basis of the biometric signal at inspection time, and the normal physiological parameter time-series data; and a disturbance degree determination unit for determining the disturbance degree of the biometric rhythm at the inspection time of the subject on the basis of the shift amount between the phases.
