Psychophisiological correction of the human state

During adaptive oscillatory biofeedback control a patient receives some information about the own cardiorhythm dynamics. Modulation of cardiorhythm is fulfilled at the expense of the special rhythm of breath under the continuous visual control and used for human state modification. 85 patients suffered with neuro- circulatory distonia had got the complete cycle of cardiotraining. Electroencephalogram, respiration, some parameters of cardiovascular system, psychological tests were registered besides cardiorhythmogram. Biofeedback control as a diagnostics shown that patient’s cardiorhythmogram can be separated into 3 types: I type - breath arrhythmia, localization of own harmonics in range of slow waves, II - breath arrhythmia, localization of own harmonics in range of high waves, III - absence of breath arrhythmia. Voluntary cardiorhythm modulation and activation of its own harmonics are resulted in training and intensification of cardiorespiratory synchronization, formation of new rhythms in intersystem relationships. Positive clinical effect is conditioned by normalization of arterial pressure, heart rate, electroencephalogram and confirmed by objective and subjective appreciation of patient state. The improvement is caused by up and down training (inhibition/exci- tation) of the symphatovagal mechanisms in cardiorhythm regulation. There is some extension of rhythmic range in interaction of cardiovascular and respiratory systems.
