[Tetralogy of Fallot. Physical work capacity after its total correction].

Results of exercise tests in 21 children after total correction of Fallot tetralogy (mean 5 years after surgery) are reviewed. Maximal exercise capacity recalculated for body mass and for total body area was approximately 60% of normal values. Maximal heart rate was lower than among healthy children. There was no statistical correlation between exercise capacity nad age while operated, nor time after surgery.
