Investigation of cardiovascular adaptation to postural passive test in the course of selecting candidates for special contingent

Selection of candidates for special contingent is made with the focus on evaluation of cardiovascular functioning and adaptability to stresses, and detection of pre-disease shifts in CV regulation. Hemodynamics regulation was assessed by tilt testing of 15 essentially healthy men at the age of 18 to 34. The tilt table was initially at 0 degrees (baseline), turned at +75 degrees (20 min), and then back to 0 degrees for 5-min recovery. Simultaneously with the standard measurements of ECG and blood pressure, the myocardium state was registered with the use of KardioVizor-06; cerebral circulation was evaluated using rheoencephalography and microcirculation vessels, -ultrasonic Doppler. Three human subjects exhibited hypotensive reactions to the tilt test and two showed hypertensive reactions. However, no changes were present on ECG records. Hence, in-depth investigation of the CV reaction to tilt test is capable to reveal incipient regulatory disorders and their trend, and to assess adaptability to stresses.
