37-41. A radioisotope method of measuring separately the circulation times for the pulmonary artery and pulmonary veins is described. Combined with pulmonary scintigraphy this method has been used to investigate textile workers with lung changes. In the workers with no evidence of heart failure there was a prolongation of the pulmonary artery circulation time but no change in the pulmonary venous circulation time. In workers with signs of right heart failure there was a prolongation of right heart filling time as well as pulmonary artery circulation time but still no prolongation of the pulmonary venous circulation time. In this group the cardiac stroke volume was reduced but the output was maintained by a tachycardia. In spite of the prolonged pulmonary circulation time there was a reduction in pulmonary blood volume and poor perfusion on the scintigram.
37 - 41. 本文描述了一种分别测量肺动脉和肺静脉循环时间的放射性同位素方法。结合肺部闪烁扫描，该方法已用于研究有肺部病变的纺织工人。在无心力衰竭证据的工人中，肺动脉循环时间延长，但肺静脉循环时间无变化。有右心衰竭体征的工人，右心充盈时间以及肺动脉循环时间均延长，但肺静脉循环时间仍未延长。在这组人群中，心搏量减少，但通过心动过速维持心输出量。尽管肺循环时间延长，但肺血容量减少，闪烁扫描显示灌注不良。
