摘要:
In some embodiments, a device to measure a shape of cyclic variation of heart rate (CVHR) comprises a processor to detect CVHR from time series data of cardiac or pulse wave inter-beat interval, heart rate, or pulse rate; acquire at least one shape property index with respect to a waveform of the detected CVHR; and evaluate health risk based on the at least one shape property index. The CVHR appears periodically in the time series data. The at least one shape property index is selected from the group consisting of an amplitude of the CVHR (ACV), a slope, a ratio of the ACV to a duration, and an area. The health risk is inversely correlated with an intensity of a heart rate response determined from the at least one shape property index.
