Preschool children and adults with visual impairments and healthy subjects were examined at rest and after local muscular efforts with the use of a hand dynamometer. In contrast to healthy children, a retarded development of the structure of the cardiac rhythm was found in children with visual impairments. These children, like adults with similar impairments, displayed a high degree of strain of the central mechanisms of cardiac regulation. © Pleiades Publishing, Inc. 2007.
