Abstract:
1. A living body state monitor apparatus comprising: a living body information acquisition device to acquire living body information containing an electrocardiography waveform and a pulse waveform with respect to a living body of a user; an irregular heartbeat detection section to detect an irregular heartbeat from the electrocardiography waveform; a pulse wave feature quantity extraction section to extract a pulse wave feature quantity from a pulse wave corresponding to the irregular heartbeat; a living body state determination section to determine a danger degree on living body state of the user using both first information and second information, a living body information storage device to store an irregular heartbeat and a pulse wave feature quantity, wherein the living body state determination section determines a danger degree on living body state using a contrast result between (i) a pulse wave feature quantity, which is within a past predetermined time period and stored by the living body information storage device, and (ii) a pulse wave feature quantity extracted by the pulse wave feature quantity extraction section.
