Title:
INSTRUMENT FOR ANALYZING AUTONOMIC NERVOUS RHYTHM
Document Type and Number:
Japanese Patent JP2004283523
Kind Code:
A
Abstract:

To reveal correlation between sympathetic nerve and parasympathetic nerve functions for determining the circadian rhythm of an autonomic nervous system by detecting autonomic nervous rhythm inherent in heart beat change in 24 hours.

A heart beat measurement input part 1 measures the number of heart beats for 24 hours and time sequential data at RR interval. A data analyzing part 2 performs FFT processing and reverse FFT processing. Then the autonomic nervous rhythm in a 24-hour period inherent in the heart beat change is determined and evaluated.
