ВЛИЯНИЕ ЭМОЦИЙ, ИНДУЦИРОВАННЫХ ЗВУКАМИ, НА ВАРИАБЕЛЬНОСТЬ СЕРДЕЧНОГО РИТМА

Abstract

The level of knowledge of increased emotional response may differ significantly from individual interpersonal dynamics and the etiology of psychopathology. Heart rate variability (HRV) analysis is an objective measure for assessing a regulated emotional response. At present, it remains unclear to what extent the valency of emotions affects the central and peripheral mechanisms of heart rhythm regulation; this is especially true of the emotions induced by listening to sound. a set of precise indicators of perception, in the experiments of which we observed comparable dynamics of HRV indicators, which are significant vegetative manifestations of an emotional response to a stimulus. It was found that stimuli with a negative emotional response cause a significant decrease in total heart rate variability (SDNN) and the severity of fast heart rates (RMSSD) against the background of heart rate. Negative emotions decrease, and positive emotions increase in the severity of respiratory arrhythmias (LF and HF), which disrupts the stabilization of the function of the nervous part of the autonomic nervous system (ANS). In addition, listening to a sound with a negative emotional connotation leads to a significant modulation of the internal rhythm, the dynamics of the heart, which is manifested by changes in the shapes and sizes of clouds on the Poincaré graph. The scope of the results of our study may lead to the emergence that the occurrence of background phenomena, as a partial natural landscape, may manifest itself in a significant degree of activity of the ANS and, thus, relates to the risk of spreading a widespread disease related to vegetative volume dysfunction.
