Apparatus and method for analyzing heart-rate variability based on electrocardiogram information
First Claim
1. A heart-rate variability analysis apparatus comprising:
- an electrocardiogram information detecting unit configured to detect electrocardiogram information about an object to be diagnosed;
a heart-rate signal calculating unit configured to calculate a heart rate signal indicative of a heart rate of the object from the electrocardiogram information;
a breathing signal calculating unit configured to calculate, from the heart rate signal, a breathing signal in which a breathing state of the object is reflected; and
a heart-rate-variability information providing unit configured to provide variability information of the heart rate of the object in which the breathing state of the object is reflected, on the basis of both of the heart rate signal and the breathing signal.

Abstract
A heart-rate variability analysis apparatus comprises an electrocardiogram information detecting unit, heart-rate signal calculating unit, breathing signal calculating unit, and heart-rate-variability information providing unit. Of these, the electrocardiogram information detecting unit detects electrocardiogram information about an object to be diagnosed. The heart-rate signal calculating unit calculates a heart rate signal indicative of a heart rate of the object from the electrocardiogram information. The breathing signal calculating unit calculates, from the heart rate signal, a breathing signal in which a breathing state of the object is reflected. The heart-rate-variability information providing unit provides variability information of the heart rate of the object in which the breathing state of the object is reflected, on the basis of both of the heart rate signal and the breathing signal. Thus, the heart-rate fluctuations can be measure with higher-precision.
