METHOD FOR ANALYSIS OF HEART RATE REGULATION STRAIN BY APPLICATION OF THE OVERALL LOGARITHMIC INDEX TO THE HOLTER ELECTROCARDIOGRAM MONITORING.

Studies of human adaptation to extended exposure in extreme environments necessitate the development of integral indexes for quantitative evaluation of the functional systems of organism. The study was performed using an integral overall logarithmic index to analyze changes in heart rate variability (HRV)' over 20-hour monitoring of patients examined in a hospital. HRV-evidenced adaptation processes were compared to the data of Holter monitoring of patients and normal values for healthy people under 30 years of age.
