Spectral independent component analysis of heart rate variability
(Харкiвський нацiональний унiверситет iм. В.Н. Каразiна, 2005) Martynenko, A.V.; Antonova, A.S.; Yegorenkov, A.M.
Formal mathematical procedure of developed Spectral Independent Component Analysis (SICA) of heart rate variability (HRV) allows to obtain no more than three components forming the rhythmogramm of healthy person. This fact rationally represents physiological hypotheses about regulation systems taking part in forming HRV phenomenon. Applying SICA to HRV approves itself on timing intervals form 3 to 15 minutes. Вreaking the low limit of this timing interval causes essential worsening of quality of ICA components forming the rhythmogramm. Optimal application of SICA for splitting initial registered HRV signal into components is using SICA with five-minute HRV registering protocol.
