FIELD: medicine.

SUBSTANCE: invention refers to rehabilitation and preventive medicine, cardiology, therapy. It involves drug-induced therapy and a course of cardiorespiratory training with biological feedback (BF) presenting a cardiorhythmography (CRG) and a reference cyclic curve (RCC) to the patient to be matched under continuous visual control. It is followed by active (BF-assisted) and non-active (BF-unassisted) 2-minute tests with the first and last test of each session are non-active (NT). The first NT involves recording reference data of patient's cardiorespiratory system with evaluating the parameters as follows: RCC amplitude, period and continuous component matched with average heart rate on the following active test (AT). The test are automatic, individual for the patient as for the moment of testing with the use of an apparatus for functional psychophysiological correction comprising units described in the patent claim. Each following AT requires forming RCC with the use of average heart rate, amplitude and period on the basis of spectral analysis of CRG and CC of the previous AT. In the beginning of the procedure, the patient is set up to successful completion of the task, 5 s after the beginning of each AT, an audio signal (1 kHz, 300 ms, 30 dB above a threshold of audibility) is supplied. Before the beginning of the course and after each session and the whole course, the patient is tested to determine a level of reactive and personal anxiety and depression by stating the required number of sessions for recovery of cardiorespiratory synchronisation and normal heart rate and blood pressure. Before the first NT and after each AT, capnometry is used to determine the concentration of CO₂ in expired air. If observing decrease, respiratory depth is corrected. If maintaining CO₂ in expired air after each following AT less than 95% from reference, respiratory depth is corrected during the following AT under control of capnometry to achieve the concentration of not less than 95% from reference. The therapeutic course includes at least 5 sessions, 1 session daily or every second day to recover the respiratory pattern lost due to the disease and the biorhythmological structure of heart rate.

EFFECT: method eliminates subjectivity of the respiratory parameters specified by a searcher, and hyperventilation syndrome due to objective control of respiratory depth with improved heart rate variability.
