Document Type and Number:
WIPO Patent Application WO/2020/050067
Kind Code:
A1
Abstract:
A method includes: acquiring electrocardiogram data of a subject; acquiring pulse wave data of the subject; calculating RR intervals in a predetermined time interval based on the electrocardiogram data; calculating pulse wave transit times (PWTT) in the predetermined time interval based on the electrocardiogram data and the pulse wave data; calculating a pulse wave transit time variation (PWTTV) in the predetermined time interval based on the PWTT in the predetermined time interval; determining whether the PWTTV in the predetermined time interval satisfies a predetermined condition associated with previously calculated PWTTV or not; calculating corrected values (PWTT') of the PWTT based on the PWTT and the RR intervals in a case where the PWTTV does not satisfy the predetermined condition; and determining candidate values (PWTTc) of the PWTT based on the PWTT and PWTT'.
