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.

Abstract: According to the present invention, blood pressure surges is detected from time-series data on blood pressure of a subject that varies with pulsation based on predetermined determination criteria. A feature amount indicating a characteristic of each blood pressure surge thus detected is obtained. Statistical processing is performed on an occurrence number of the blood pressure surges thus detected and/or the feature amount to obtain a statistical amount for each of time slots. A required attention degree indicating a level of attention being required to the blood pressure surge is obtained for each of the time slots based on the statistical amount of the occurrence number of the blood pressure surges and/or the feature amount. The required attention degree thus obtained and/or the statistical amount are displayed side by side for each of the time slots on a display screen.
