Abstract
An RRI measurement device includes: an R wave detection unit configured to detect a peak point of an R wave from a sampling data sequence of an electrocardiogram signal of a subject; an R wave detection unit configured to estimate a waveform near the R wave of the electrocardiogram signal on the basis of the peak point of the R wave detected by the R wave detection unit and sampling data of the electrocardiogram signal before and after the peak point and to detect the peak point of the R wave again on the basis of the estimated waveform; and an RRI calculation unit configured to calculate an RRI on the basis of time-series data of the peak point of the R wave detected by the R wave detection unit.
