ejection fraction

基本解释

We saw an improvement in the ejection fraction, in the ability of the heart to pump out blood, of 25%.
我们看到，在药物注射部位，心脏的泵血功能提高了25%。
Design, Setting, and Patients Multicenter, randomized controlled trial among 2331 medically stable outpatients with heart failure with left ventricular ejection fraction of 35% or less.
试验设计、设定与病人多中心随机对照试验，2331名医学上稳定的门诊心衰患者，左心室射血分数小于等于35%。
The patients' left ventricular ejection fraction ( EF ) and the peak filling rate ( PFR ) were decreased , and the time of peak filling rate ( TPFR ) was prolonged.
发现病人的左室射血分数（EF）下降，高峰充盈率（PFR）下降，高峰充盈时间（TPFR）延长。

Half of all heart attack survivors have a damaged heart called low ejection fraction.
