A 37-year-old athlete completed invasive endurance (90 km) bicycle exercise testing for right ventricular pressure-volume analysis. Increased right ventricular afterload caused declines in ventricular-arterial coupling and cardiac output, causing increased arteriovenous oxygen difference to maintain oxygen uptake. These findings demonstrate effects of changes in right ventricular performance on exercise capacity. ().
一名37岁的运动员完成了用于右心室压力-容积分析的侵入性耐力（90公里）自行车运动测试。右心室后负荷增加导致心室-动脉耦合和心输出量下降，致使动静脉氧差增加以维持摄氧量。这些发现证明了右心室功能变化对运动能力的影响。（）
