Title:
RRI MEASUREMENT DEVICE, RRI MEASUREMENT METHOD, AND RRI MEASUREMENT PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/091195
Kind Code:
A1
Abstract:
This RRI measurement device comprises: an R wave detection unit (223) which detects a peak point of an R wave from a sampling data series of an electrocardiogram signal of a subject; an R wave detection unit (224) which estimates 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 (223) and sampling data of the electrocardiogram signal before and after of the peak point, and redetects the peak point of the R wave on the basis of the estimated waveform; and an RRI calculation unit (225) which calculates an RRI from the time series data of the peak point of the R wave detected by the R wave detection unit (224).
