APPLICATION OF INFORMATIVE HEART RATE VARIABILITY, HEMODYNAMICS AND OXYGEN UPTAKE VALUES FOR OPTIMISATION EXERCISE TRAINING PROGRAMME

The aim of this study is to assess the peculiarities of heart rate variability (HRV), hemodynamics and oxygen uptake data during functional testing procedures in post - MI patients at various risk groups and to use the infor?mative values for optimisation the intensity of exercise training programme. The peculiarities and significance of heart rate variability, hemodynamics and O2 uptake data were assessed in 558 post - myocardial infarction patients, subdivided into low (group 1, 44 pts), intermediate (group 2, 221 pts) and high (group 3, 293 pts) risk groups. Clinical investigation, followed by typical instrumental (ECG, echocardiography etc.) was performed for every patient at the beginning of search. A computerised analysis of heart rate variability (SDNN, respiratory sinus arh?ythmia ? RA, HR power - spectrum components: very low frequency (VLFC), low frequency (LFC), and high fre?quency (HFC), maximum HR values in response to the AOT (RRB), the extent of response (DRRB) as well as hemodynamics (method rheografy) and oxygen uptake parameters (VE, VO2, VE/VO2, VE/VCO2) during an ac?tive orthostatic test (AOT), bicycle exercise or spiroergometric test was estimated. On the ground of the informa?tive parameters of autonomic HR control, hemodynamics and O2 uptake responses to the workload, an algorithm for the optimisation of an exercise-training programme was proposed and used for training patients with coronary artery disease.
