Exercising pulmonary blood flow was estimated from indicator-dilution curves in a patient with the infrequent combination of rheumatic mitral stenosis and anomalous pulmonary venous connection from the left lung. During supine exercise against progressively increasing external workloads, the proportion of flow to each lung remained nearly constant. The pulmonary vascular resistance was highest in the left lung, which emptied into the low-pressure systemic vein. Although right and left atrial pressures differed markedly during supine exercise, the proportion of pulmonary blood flow shunted to the systemic venous sytem remained essentially unchanged.
通过指示剂稀释曲线，对一名患有风湿性二尖瓣狭窄合并罕见的左肺异常肺静脉连接的患者进行了肺血流估算。在仰卧位运动过程中，随着外部负荷逐渐增加，流向每侧肺的血流比例几乎保持恒定。左肺的肺血管阻力最高，其血液流入低压体静脉。尽管仰卧位运动时右心房和左心房压力有显著差异，但分流至体静脉系统的肺血流量比例基本保持不变。
