An apparatus for blood pressure measurement capable of heart function assessment for readily putting on a living subject, comprising an inflatable cuff including a pressure-pulse-wave sensor, which is combined into one body with the cuff at an upper-stream side end of the cuff, when wrapped around an upper-arm portion, so as to detect, at the upper-stream side than a blood-flow stopped position, the pressure-pulse-wave, which is of the same waveform as an aorta waveform while blood-flow is stopped, and an ejection time calculating means (a heart function parameter calculating means), by which an ejection time ET can be calculated as a time difference from a rising-point to a dicrotic notch of the pressure-pulse waveform for heart function assessment. Since a blood pressure BP also can be measured with the cuff, all the putting on the living subject, that is needed to measure the blood pressure and heart-function is to put on the cuff, which is combined with the pressure-pulse wave sensor, and to wrap the cuff around the upper-arm portion, therefore, putting-on becomes more simple and easier for measuring a heart function parameter and a blood pressure.
