A physiological information processing method includes: acquiring electrocardiogram data of a subject; acquiring pulse wave data of the subject; measuring the heart rate based on the electrocardiogram data; measuring the pulse wave transit time based on the electrocardiogram data and the pulse wave data; calculating a cardiac output based on the pulse wave transit time and heart rate which have been measured; calculating the systemic vascular resistance; and correcting the calculated cardiac output based on the systemic vascular resistance.

Physiological information processing apparatus and physiological information processing method

A physiological information processing method includes: acquiring electrocardiogram data from a subject; acquiring pulse wave data from the subject; measuring a plurality of RR intervals based on the acquired electrocardiogram data; measuring a plurality of pulse wave transit times based on the acquired electrocardiogram data and the acquired pulse wave data; calculating, based on the measured RR intervals and the measured pulse wave transit times during a given time period, a parameter related to correlation between the measured RR intervals and the measured pulse wave transit times; and outputting the calculated parameter.
