Biometric information measurement device, control method of biometric information measurement device, and program

A biological information measurement device used by being worn on a wrist of a human body, the biological information measurement device comprising:

• a blood pressure measurement unit configured to measure a blood pressure of the human body;
• an electrocardiographic waveform measurement unit which includes a plurality of electrodes and is configured to measure an electrocardiographic waveform of the human body;
• an electrode contact state detection unit configured to detect a contact state of the human body with the plurality of electrodes;
• a position detection unit configured to detect a position of the device;
• and
• a controller which controls the electrocardiographic waveform measurement unit and the blood pressure measurement unit,
• wherein the controller includes
• a first correctness determination unit which determines, on a basis of an output of the position detection unit, correctness as to whether or not a wrist of the human body on which the device is worn is positioned at a height within a predetermined range,
• a second correctness determination unit which determines, on a basis of an output of the electrode contact state detection unit and information the baseline fluctuation of the electrocardiographic waveform and/or the posture fluctuation of the device, whether or not the human body is stably in contact with the plurality of electrodes when a determination result of the first correctness determination unit indicates correctness, and
• a collective measurement control unit which automatically performs control to collectively execute blood pressure measurement of the human body by the blood pressure measurement unit and measurement of an electrocardiographic waveform of the human body by the electrocardiographic waveform measurement unit, on condition that at least a determination result of the second correctness determination unit indicates correctness.
