[Alternative biocontrol as a psychophysiological mechanism of functional adaptive self-regulation].

Study of voluntary autoregulation of the heart rate (HR) by means of artificial biofeedback (BFB) using a display, has revealed the possibility of changing the HR voluntarily within a wide range of (from 50 to 140 beats per minute). Respective fluctuations occurred in the arterial pressure. A decrease in the HR and reactive alarm, increase in the self-assessment of physical state, activity, mood and work level occurred in result of the HR-BFB training.
