PROBLEM TO BE SOLVED: To provide a technology to predict an extent of a health risk such as a mortality rate in a predetermined period of time more accurately than ever before.SOLUTION: A CVHR shape measurement device 2 includes CVHR detection means and CVHR shape characteristic index acquisition means. The CVHR detection means detects a cyclic variation of heart rate (CVHR) that periodically appears from data that indicates a cycle or a frequency of a heartbeat or a pulse in a time series manner. The CVHR shape characteristic index acquisition means acquires at least one of the shape characteristic indexes of an amplitude (amplitude of cyclic variation or ACV), an inclination, a ratio of the amplitude to a duration, and an area for a waveform of the CVHR detected by the CVHR detection means.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】所定期間内における死亡率などの健康リスクの程度を従来よりも正確に予測できる技術を提供する。【解決手段】CVHR形状測定装置2は、CVHR検出手段と、CVHR形状特性指標取得手段と、を備える。CVHR検出手段は、心拍又は脈拍の周期又は周波数を時系列で示したデータから、周期的に出現する心拍数周期性変動(CVHR)を検出する。CVHR形状特性指標取得手段は、CVHR検出手段で検出されたCVHRの波形に対して、次の形状特性指標:振幅(amplitude of cyclic variation,ACV)、傾き、持続時間に対する振幅の比、及び面積の少なくとも1つを取得する。【選択図】図1
