用~(113m)In和γ-心功能仪测定13例正常人右室射血分数为52±7.5％,7例肺心病心功能代偿期右室射血分数为57±3.5％,24例肺心病心功能不全 I°右室射血分数为43±4.3％,12例肺心病心功能不全Ⅱ°右室射血分数为33±7.2％,8例肺心病心功能不全Ⅲ°右室射血分数为28±5.5％,7例肺心病心功能不全极重型右室射血分数为14±2.7％。除代偿期外,其它各组比较均有显著性差异,ρ< 0.05或<0.01。本文提示:γ-心功能仪可以用来估价肺心病患者各期心功能损害情况,对临床肺心病心功能分度有实用参考意义。
The right ventricular ejection fraction of 13 normal subjects was 52 ± 7.5% with ~ (113m) In and γ-cardiac function test. The RV ejection fraction in 7 patients with cor pulmonale was 57 ± 3.5% Cardiac insufficiency I ° right ventricular ejection fraction of 43 ± 4.3%, 12 cases of cor pulmonale Ⅱ ° right ventricular ejection fraction of 33 ± 7.2%, 8 cases of cor pulmonale heart failure Ⅲ ° right ventricular injection Blood score of 28 ± 5.5%, 7 cases of pulmonary heart disease, severe right ventricular ejection fraction 14 ± 2.7%. Except for compensatory period, the other groups showed significant differences, ρ <0.05 or <0.01. This article suggests: γ-cardiac function can be used to estimate heart failure in patients with various stages of pulmonary heart disease, clinical pulmonary heart disease has practical reference significance.
