Question: what is the difference between stroke volume and ejection fraction?
Answer: This is called the stroke volume or SV, and the formula is: (stroke volume (SV)=end diastolic volume (EDV)–end systolic volume (ESV)). Ejection fraction—How efficient is the ventricle at pumping blood? The ejection fraction or EF is an indicator of how efficient the ventricle is at emptying itself.
