<P>PROBLEM TO BE SOLVED: To improve monitoring accuracy when the condition of a living body is monitored by using CVRR and an autonomic nerve activity index. <P>SOLUTION: An autonomic nerve activity computing section 24 computes the autonomic nerve activity index showing the activity of the autonomic nerve by performing a frequency analysis (spectrum analysis) to electrocardiogram data in a prescribed period, e.g. 60 seconds, every time an R wave is detected in the electrocardiogram data measured by an electrocardiogram monitor 14. A CVRR computing section 25 computes CVRR on the basis of the electrocardiogram data in the same prescribed period as the prescribed period for computing the autonomic nerve activity index, every time the R wave is detected in the electrocardiogram data. A control device 18 two-dimensionally displays the relation between the autonomic nerve activity index computed by the autonomic nerve activity computing section 24 and the CVRR computed by the CVRR computing section 25 to a display device 22. <P>COPYRIGHT: (C)2011,JPO&INPIT |
