<p><P>PROBLEM TO BE SOLVED: To provide an autonomic nerve index measuring apparatus for precisely measuring an autonomic nerve index. <P>SOLUTION: The autonomic nerve index measuring apparatus comprises a detection rate calculating section 13 for calculating a detection rate that shows the ratio of the sum of the number of interval data number which represents the number of interval data, each piece of which shows time interval of a period of pulse or heart rate waveform, generated within a predetermined reference time period and the number of error data which represents the number of error data, each of which shows contents of errors occurred when generating interval data, generated within a predetermined reference time period to the number of interval data, and an autonomic nerve index calculating section 14 for calculating an autonomic nerve index that shows activity condition of the autonomic nerve on the basis of the interval data generated within the reference time period when the detection rate is larger than a predetermined first threshold upon comparison of the detection rate and the first threshold. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
