Abstract
An apparatus for measuring a blood pressure of a living subject, including a blood pressure measuring device which measures a blood pressure value of the subject, a first memory which stores a plurality of blood pressure values measured by the blood pressure measuring device, in an order of measurement of the blood pressure values, a pulse wave detecting device which detects a pulse wave produced from an arterial vessel of the subject in synchronism with heartbeat of the subject while each of the blood pressure values is measured by the blood pressure measuring device, a second memory which stores a waveform of the pulse wave detected by the pulse wave detecting device, in the order, the second memory storing the respective waveforms of the pulse waves each of which is detected by the pulse wave detecting device while a corresponding one of the blood pressure values is measured by the blood pressure measuring device, and an output device which outputs the blood pressure values stored in the first memory, in the order, and a plurality of curves respectively representing the waveforms stored in the second memory, in the order, in a side-by-side relation with each other.
