TECHNOLOGICAL INNOVATION INDEPENDENT COMPONENT ANALYSIS OF HEART RATE VARIABILITY
Keywords:
rhythmogramm, independent component analysis, heart rate variabilityAbstract
The article is devoted to statistical approach that based on method of splitting registered composite rhythmogramm to its independent components, each formed by corresponding regulating units of an organism. Formal mathematical procedure of independent component analysis (ICA) of heart rate variability (HRV) allows to obtain no more than three components forming the rhythmogramm of health person. This fact rationally represents physiological hypotheses about regulation systems taking part in forming HRV phenomenon. ApplyingICAto HRV approves itself on timing intervals form 4 to 15 minutes. Вreaking the limit of this timing interval causes essential worsening of quality of components forming the rhythmogramm. Optimal application ofICAfor splitting initial registered HRV signal into components, according to quality, is usingICAwith five-minute HRV registering protocol.
