We evaluated the maximal exercise tolerance using cardiopulmonary exercise testing, and investigated the relation of the hemodynamic parameters such as mean pulmonary artery pressure (PAm) and pulmonic-to-systemic flow ratio (Qp/Qs) to exercise tolerance in 18 adult patients consecutively. All the patients had atrial septal defect (ASD). Maximal oxygen uptake (VO2 max) averaged only 21.6±5.6 ml/min/kg and 63.5±16.2% of the predicted values (VO2max). And anaer-obic threshold averaged 12.5±2.3 ml/min/kg and 56.7 ±12.4% of the predicted values.
