What is normal ejection fraction?

• A. 50-70%
• B. 30-50%
• C. 70-90%
• D. 40-60%

Answer: (A)

Ejection fraction shows how much of the ventricle’s filling blood is pumped out with each heartbeat, expressed as a percentage. It’s calculated as stroke volume divided by end-diastolic volume. In a healthy heart, systolic function keeps the ejection fraction in roughly 50-70%. This range reflects normal pumping efficiency; values below 50% indicate reduced systolic function (heart failure with reduced EF), while higher values are not typically considered normal for the general population. So, 50-70% is the standard normal range.
