Exercise and Cyanotic Diseases

Moderate levels of activity are usually tolerated well, but careful exercise testing is important before setting limits. This should be done periodically as there may be a decline in tolerance over time. On the whole, exercise should be restricted to moderate levels of intensity and duration, especially if atrial arrhythmias or other conduction anomalies are present. The effects of the repair operations for certain cyanotic diseases (e.g. the Fontan operation) on the performance of the lungs and on the anatomy of the thorax may also be factors in determining safe levels of exercise.

Anyone with congenital heart disease, repaired or non-repaired, should consult with their cardiologist about physical activity to review the risks.
