Moskovzeva N.I., Mironzev O.V. DYNAMICS OF HEMODYNAMIC PARAMETERS OF THE PATIENTS WITH OLD MYOCARDIAL INFARCTION DURING ADAPTATION TO PERIODIC ALTITUDE CHAMBER HYPOXIA The authors study an effect of adaptation to periodic altitude chamber hypoxia (APACH) on hemodynamic parameters of cardio ischemia patients with old myocardial infarction.
