Experimental Observation of the Self-Oscillatory Dynamics of the Regulation Contours of the Cardiovascular System

摘要: In this work, we experimentally study the heart rate variability, photoplethysmograms, and electroencephalograms of healthy subjects in course active experiments with respiration, whose varied according to a known law. On basis measured signals electroencephalograms, it is shown that low-frequency regulation processes frequencies below 1 Hz interact each other are significantly influenced by respiration process. The obtained results indicative presence several vegetative-regulation centers activity manifested dynamics electroencephalograms.
