[Physical fitness of children after cardiosurgical correction of an atrial septal defect type II].

Physical fitness of 17 children aged 8-12 years being 4-7 years after cardiosurgical correction of interatrial defect of the heart (ASD II) was studied. The results were compared with the ones obtained in 14 healthy children of the same age. The parameters of gas exchange, gasometry, heart rate, ECG, arterial blood pressure were determined during supervised physical fitness test. The power of the children and so called anaerobic threshold (according to Beavers method) were evaluated during the exercise test performed on mechanical treadmill, as well. No significant differences of the studied classical physical fitness parameters between both studied groups were observed. On the other hand, the use of a log-log transformation method indicated that the children after cardiosurgical correction achieved the anaerobic threshold at lower exercise intensity. This fact is connected with lower physical performance of these children as compared to the control group.
