CORRELATION ANALYSIS

The Correlation Analysis gives the total spectral correlation between the HRV Analysis - R-R intervals and the amplitude of the plethysmographic waves or between R-R intervals and I-I intervals - inspiration waves. The obtained value is ‘zero’ harmonic of the correlation spectrum.

In this way, the following is derived:

*   Total spectral correlation power;

*   Power associated with “long spectral waves” (Pl),

*   Power associated with middle spectral waves (Pm);

*   Power associated with “short waves” (Ps) of the amplitude correlation spectrum;

*   Maximal spectral power (as amplitude (s/Hz2) and frequency (Hz)

Imaginary and phase correlation spectrum can be also selected. A decreased spectral correlation (coherence) speaks about decrease in the ability to adapt towards extreme stresses.

The work with this option presumes more detailed knowledge and education.
