[Reaction of the cardiovascular system in preschool children with vision defects to the active orthostatic test].
75 children with vision defects and 79 healthy children from 4.5 till 6.5 years were inspected by method of thonometry, electrocardiography and HRV during carrying out the active tilt-test. It is revealed that system hemodynamics of preschool children with vision defects is characterized by a plenty of inadequate reactions to the active tilt-test: in girls with vision defects hyperdiastolic reactions prevailed and in boys with vision defects hypodiastolic reactions prevailed. Boys with vision defects were characterized by a decrease in vegetative and hemodynamics reactivity that is connected with a decrease in reactivity of sympathetic nervous system. Cardiovascular system of preschool children with vision defects is characterized by a decrease in reserve opportunities.
