1. A pulse wave analysis device comprising:
- a storage unit for storing a pulse waveform for a plurality of beats;
an analysis processing unit configured to;
(1) integrate pulse waveform shapes of each beat that constitute the pulse waveform for the plurality of beats by combining the plurality of beats so as to obtain an integrated pulse waveform shape,(2) determine a degree of approximation between the integrated pulse waveform shape and each of the plurality of beats,(3) calculate a pulse wave analysis index for the plurality of beats after excluding, as a calculation target, a beat for which the degree of approximation between the integrated pulse waveform shape and the pulse waveform shape of the beat is low, and(4) calculate a degree of stability of beating by integrating the degrees of approximation of each pulse waveform shape used in the calculation of the pulse wave analysis index; and
an output unit that outputs the calculated pulse wave analysis index as an analysis result and the degree of stability as an index indicating reliability of the pulse wave analysis index.

Abstract
A pulse wave analysis device stores a pulse waveform for multiple beats, and calculates a pulse wave analysis index by analyzing the pulse waveform. In the calculation of the pulse wave analysis index, pulse waveform shapes of each beat that constitute the pulse waveform for multiple beats are integrated, and beats for which a degree of approximation between the integrated pulse waveform shape and the pulse waveform shape of the beat is low are excluded as targets of calculation of the pulse wave analysis index.
