Sažetak
Heart rate variability parameters (derived from RR intervals) are good indicators of the effects of different psychophysiological conditions (e.g., stressful situations, emotional excitement, and physical load) on cardiac activity. Their particular value is reflected in good predictability in the occurrence and course of various diseases. Cardiac activity parameters are predictable for general health probably because heart activity is largely determined by the autonomic nervous system (sympathetic and parasympathetic) and the autonomic nervous system modulates most other organs and systems. It is generally believed that cardiac RR intervals are non-invasive indicators of autonomic nervous system activity. We can calculate more qualitative and quantitative parameters that indicate the various aspects of cardiac dynamics from cardiac R-R intervals, but if we want to observe the functionality of the autonomic nervous system, it is necessary to perform a power spectral analysis. This mathematical procedure divides cardiac activity in different frequency bands, which are associated with the modulation of different components of the autonomic nervous system (sympathetic/parasympathetic). This paper describes the logics of spectral analysis procedure on cardiac R-R intervals, the parameters of the analysis, their interpretation and physiological connection with individual components of the autonomic nervous system, and the practical implications arising from this type of cardiac dynamics analysis.
