Biological information measurement apparatus, biological information measurement system, biological information measurement method, and program

A biological information measurement method comprising:

• acquiring at least first waveform information relating to a first waveform representing a beat of a measurement subject measured at a first measurement site, and as second waveform information relating to a second waveform representing the beat of the measurement subject measured at a second measurement site different from the first measurement site, information relating to a timing corresponding to a second feature which is a characteristic feature of the second waveform;
• and
• calculating, based on the first waveform information and the second waveform information, a pulse wave transit time, which is a difference between a timing corresponding to a first feature which is a characteristic feature of the first waveform and the timing corresponding to the second feature which is a characteristic feature of the second waveform.

A program for causing a computer to realize:

• a function for acquiring at least first waveform information relating to a first waveform representing a beat of a measurement subject measured at a first measurement site, and as second waveform information relating to a second waveform representing the beat of the measurement subject measured at a second measurement site different from the first measurement site, information relating to a timing corresponding to a second feature which is a characteristic feature of the second waveform;
• and
• a function for calculating, based on the first waveform information and the second waveform information, a pulse wave transit time, which is a difference between a timing corresponding to a first feature which is a characteristic feature of the first waveform and the timing corresponding to the second feature which is a characteristic feature of the second waveform.
