PROBLEM TO BE SOLVED: To provide a biomonitoring device capable of efficiently detecting an arrhythmia even in the case of inspection over a long time.SOLUTION: A biomonitoring device 1 includes a change point extraction unit 111 and a measurement unit 14. The change point extraction unit 111 extracts a plurality of change points where the tendency of the pulse rate of a monitor target U is changed, from first time series data. When the pulse rate of the monitor target U after the latest change point satisfies a first condition, the measurement unit 14 measures the pulse rate of the monitor target U at a second interval shorter than a first interval.SELECTED DRAWING: Figure 2ACOPYRIGHT: (C)2020,JPO&INPIT
