[Exercise tolerance in children with primary bicuspid valve prolapse syndrome].

Exercise tolerance in children with the primary bicuspid valve prolapse syndrome has been evaluated with ergometric test. Additionally, an effect of environmental factors on exercise tolerance has been assessed in children from the urban and rural areas. A good tolerance of submaximal loads has been shown in both groups. However, the obtained results have been significantly more favourable in children from rural areas. The authors have concluded that limitation of exercise in children with bicuspid valve prolapse is not necessary during an intensive growth.
