AIM OF THE STUDY. The Authors have examinated 22 children (16m and 6f), mean age 9.64 ± 2.63 years, range 5-15, after total correction for Tetralogy of Fallot, to evaluate the response of their cardiovascular apparatus during an exercise testing on treadmill (Bruce protocol). METHODS. Parameters examined: exercise duration, maximal heart rate (HR), maximal systolic blood pressure (max BP), non invasive cardiac output at rest and at the peak of exercise (CO), arterial oxygen saturation; lung function test at rest, echocardiogram and 24 hours Holter monitoring. Control group: 22 healthy peers, same gender, height and weight, not practising competitive sports. RESULTS. The exercise duration was significantly lower in the first group (77.8 ± 11.8%; 86.5 ± 8.2%; P = 0.006). Also max HR and max BP were significantly lower (max HR: 162 ± 12 b/m'; 187 ± 8 b/m'; P = 0.000), (max BP: 119 ± 9 mm Hg; 126 ± 12 mm Hg; P = 0.042). There were no differences for CO at rest (3.70 ± 1.09 l/m'; 3.95 ± 1.07 l/m'). In the first group, CO at peak of exercise was lower but not significantly (6.51 ± 2.56 l/m'; 7.95 ± 2.77 l/m'; NS). CONCLUSIONS. These results make more complete the not invasive functional evaluation for a better follow-up of these patients and a better choice for their phisical activity.
