Abstract:
0.05) were found in ejection fraction (EF), fractional shortening of left ventricle (DD), blood flow velocity through aortic valve, blood flow velocity through pulmonary valve, E peak velocity of mitral valve, left atrial end-systolic anterior-posterior diameter, left ventricular end-systolic anterior-posterior diameter, left ventricular end-systolic left-right diameter and left ventricular end-diastolic left-right diameter after 2-4 hours of +Gz exposure. A peak velocity in mitral valve slightly increased (P
