Modern View on Heart Rate Variability in Neurocardiology

The article reviews the literature on the modern vision of the processes of heart rate variability formation in the field of neurocardiology. The main physiological principles involved in the formation of heart rate variability are considered. The authors present the main methods of studying heart rate variability, taking into account the disadvantages and advantages of each one, and discuss the significance of heart rate variability in the study of the cardiovascular system. The main factors influencing the normative indicators of heart rate variability are considered. Scientific facts indicating the functional relationship between the heart muscle and the brain are given. The issue of the relationship and balance between the sympathetic and parasympathetic nervous system is also revealed which confirms the high importance of studying heart rate variability.
