The results of the study of heart rate variability during sessions of hyperbaric oxygenation therapy (HBOT) in the patients with angina pectoris and acute myocardial infarction (AMI) demonstrated in the article. Protocol HBOT are: 1,4 ata, 60 min. We observed significant increase under HBOT the total power, parasympathetic activity and decrease the sympathetic activity. We hypotized that LF(LFn), HF(HFn), LF/HF ratio useful to control balance of the autonomic nervous system under influence of the HBOT. Selected protocol was safe and effective for patient with stable angina I-II functional class NYHA and AMI (HBOT started on 27±9 day after AMI occur). The least tolerance to the chosen protocol HBOT is revealed at the patients with stable angina III-IV functional class NYHA and unstable angina, and they require an individualization of the protocol according of dynamics of HRV during a session. The patients with the history of AMI had the lower tolerance to hyperoxya.
