Ejection fraction

射血分数（英語：ejection fraction，缩写EF）是一个心脏生理学术语，指每博输出量（英语：Stroke volume）占心室舒張末期容積（英语：End-diastolic volume）的百分比，可分为左心室射血分数（left ventricular ejection fraction，LVEF）和右心室射血分数（right

Ejection_fraction）（left ventricular ejection fraction，LVEF ）異常與否，心臟衰竭分為三類：低收縮分率心衰竭（heart failure with reduced ejection fraction，HFrEF）、心臟收縮力輕度降低心衰竭（heart
