  • Patent number: 8684938
    Abstract: A biological condition evaluation apparatus determines a symptom of a heart abnormality based on at least one index calculated from a heartbeat interval and/or a pulse interval. The apparatus determines whether it is in a referential period where an amount of change in the index is comparatively small. The apparatus determines whether a plurality of conditions are satisfied or not in an evaluation period set after the referential period. One condition is that an amount of change in the index in the evaluation period is greater than that observed during the referential period. Another condition is that a rate of change in the index is equal to or greater than a predetermined threshold value. The apparatus determines that there is a symptom of a heart abnormality, when both the conditions are satisfied.

  • Patent number: 8548578
    Abstract: A living body state monitor apparatus includes: a living body information acquisition device to acquire living body information containing an electrocardiography waveform and a pulse waveform from a user; an irregular heartbeat detection section to detect an irregular heartbeat from the electrocardiography waveform; and a pulse wave feature quantity extraction section to extract a pulse wave feature quantity from a pulse wave corresponding to the irregular heartbeat. Further, a living body state determination section is included to determine a danger degree on user's living body state using both of (A) information on kind and/or continued time period of an irregular heartbeat detected by the irregular heartbeat detection section, and (B) a pulse wave feature quantity extracted by the pulse wave feature quantity extraction section, and/or a variation of the extracted pulse wave feature quantity.
