    Abstract: According to the present invention, blood pressure surges are detected from time-series data on blood pressure of a subject that varies with pulsation based on predetermined determination criteria. For each blood pressure surge thus detected, an envelope connecting a plurality of pulse-corresponding peaks forming the blood pressure surge is acquired as an individual waveform. Statistical processing is performed on a plurality of individual waveforms to obtain a representative waveform and waveform variation among the blood pressure surges in the time-series data. On a display screen, a curve indicating the representative waveform is displayed with the curve superimposed on a region indicating the waveform variation among the blood pressure surges.
