The radionuclide right ventricular ejection fraction (RVEF) determined by means of Krypton-81m represents a simple, noninvasive, and accurate procedure to quantify the right ventricular contractility. This procedure was applied to 25 young patients with cystic fibrosis. The RVEF tended to decrease with the progression of the lung disease, as assessed by the clinical S-K score, the degree of the defects on lung scintigraphy, the PaO2, and the lung function tests. However, the decrease of RVEF in patients with marked lung function tests. However, the decrease of RVEF in patients with marked lung involvement was moderate, and terminal lung disease was sometimes associated with normal right heart contractility.
通过氪-81m测定的放射性核素右心室射血分数（RVEF）是一种简单、无创且准确的量化右心室收缩力的方法。该方法应用于25例年轻的囊性纤维化患者。根据临床S-K评分、肺闪烁显像的缺损程度、动脉血氧分压（PaO2）和肺功能测试评估，RVEF倾向于随着肺部疾病的进展而降低。然而，肺功能测试明显异常的患者中RVEF的降低程度适中，终末期肺部疾病有时与右心正常收缩力相关。
