Twenty-one patients with tetralogy of Fallot following intracardiac repair underwent a treadmill test for evaluation of their exercise capacity. They were divided into two groups according to their post-operative hemodynamic status, the good result group and the poor result group. The maximum oxygen consumption during exercise was significantly decreased in the poor result group, but that of the good result group showed no significant difference from the control group. However, the maximum heart rate in both the good and the poor result groups was significantly lower than that of the control group. Thus, the exercise tolerance in post-operative tetralogy patients was found to be within the normal range as long as their hemodynamic operative result was satisfactory, but the limited capability of increasing heart rate with exercise could present a potential problem in the long-term prognosis.
21例法洛四联症心内修复术后患者接受了平板运动试验以评估其运动能力。根据术后血流动力学状态，他们被分为两组，即效果良好组和效果不佳组。效果不佳组运动期间的最大耗氧量显著降低，但效果良好组与对照组相比无显著差异。然而，效果良好组和效果不佳组的最大心率均显著低于对照组。因此，发现只要术后血流动力学效果满意，法洛四联症患者的运动耐量就在正常范围内，但运动时心率增加能力受限可能会给长期预后带来潜在问题。
