<P>PROBLEM TO BE SOLVED: To grasp patient's mental stress situation not grasped by a state of an autonomic nerve alone. <P>SOLUTION: An electrocardiogram monitor measures electrocardiographic data of a person to be measured. An autonomic nerve activity calculation section calculates a sympathetic nerve activity index (LF/HF) indicating the activity level of the sympathetic nerve based on the electrocardiographic data measured by the electrocardiogram monitor. CVRR calculation section calculates CVRR (a coefficient of variation of R-R intervals in the electrocardiogram) based on the electrocardiographic data measured by the electrocardiogram monitor. A relationship between the sympathetic nerve activity index (LF/HF) calculated by the autonomic nerve activity calculation section and the CVRR calculated by the CVRR calculation section is two-dimensionally displayed to a display device. <P>COPYRIGHT: (C)2010,JPO&INPIT |
