[Dynamics of reserve possibilities of the cardiorespiratory system and pulmonary perfusion after surgical correction of congenital heart defects with arteriovenous blood output].

The dynamics of spiroveloergometric parameters and perfusion scintigraphy of the lungs with a postural test in 129 patients with congenital heart diseases were studied before and at different terms after surgical correction of the disease. It was established that main spiroergometric parameters were improved within the period from 3 to 6 months. However, normalization of physical working ability in the group of women took place about one year later than in men.
