Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...

Analysis of heart rate variability and clinical implications.

In the last decades analysis of heart rate variability has emerged as a new useful tool for assessing the changes in autonomic tone that influences cardiovascular function. High variability of oscillations and the integrated physiologic activities of heart and cardiovascular system isassociated with physiologic functioning. Irregularity of the length of consecutive heart cycles, designated as h...

Basic notions of heart rate variability and its clinical applicability.

Autonomic nervous system (ANS) plays an important role in the regulation of the physiological processes of the human organism during normal and pathological conditions. Among the techniques used in its evaluation, the heart rate variability (HRV) has arising as a simple and non-invasive measure of the autonomic impulses, representing one of the most promising quantitative markers of the autonom...
