Aim. Analyzing the vegetative tensity of organism» functional systems before and after surgical treatment of elderly patients with metabolic-and-dystrophic gonarthrosis. Methods. The evaluation of vegetative homeostasis, reactivity of the vegetative nervous system by the data of variation pulsometry («REAN-POLY» RGPA-6/12, Taganrog) in 60 patients with gonarthrosis at the age of 50-72 years and the disease duration — 9+1.5 years before and after surgical treatment: total tunnelization (Group I), tunnelization with osteotomy of leg bones for correction of limb biomechanical axis (Group II), treatment-and-diagnostic arthroscopy (Group III). Results. The reduction of the level of hypoxia tolerance and the decrease of the processes of general adaptation one month after surgery in Group I was registered in 40% of patients. As for patients of Group II, by the end of the period of fixation with the llizarov device — in 50%. As for those of Group III after arthroscopy — in 10% of patients. Among the patients whose 1С / 1С calculated parameter after surgical treatment was registered <1.0, its values were >10.0 before treatment in 70% of cases. At rest, marked vagotonia was registered with hypersympathicotonic reaction to orthotest, as well as with sharp decrease of the proportion of second-order slow waves while transition to standing position (VLF proportion <10.0%), thereby reflecting organism»s energy deficiency state. Conclusion. Preoperative examination. When VLF proportion after orthotest is registered <10.0%, such patients should be referred to risk group and prescribed in-depth examination. The index of centralization (1С) dynamics for orthotest (1С test/1С rest) is one of the criteria of functional recovery level for the particular patient: its increase points to the positive dynamics of restorative rehabilitative process, and the values <1.0 —to the negative one.

The research goal is to study the correlation between indices of variational pulsometry, entropy of heart rate, temporal and spectral analyses and heart rate variability in healthy patients and patients with coronary heart disease. Materials. Of the study are indicators of variational pulsometry and temporal and spectral analyses from 111 patients with coronary heart disease and in 61 healthy individuals. Results. Most parameters of HRV correlated with each other. In healthy patients the greatest independence was characterized by Mo and LF/HF, in patients with coronary artery disease — only by LF/HF Significant correlation with SDNN RMSSD, TP, LF, HF was determined. Conclusion. The variational pulsometry, temporal and spectral analyses of HRV and entropy of heart rate provide HRV assessment. The indices are interdependent and indicate interchangeability of methods
