What is the normal Ejection Fraction (EF) at rest?

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

Answer: (C)

The normal Ejection Fraction (EF) at rest typically ranges from 50% to 70%. An EF within this range indicates that the heart is effectively pumping blood and is functioning well in terms of its contractility. While the lower limit of normal is considered to be around 50%, most healthy individuals tend to have an EF that falls closer to the upper limit, around 60% to 70%. This measurement is crucial as it reflects the percentage of blood that is ejected from the heart with each contraction and serves as an important indicator of cardiac health. Ejection Fraction can vary based on factors such as age, gender, and overall health, but recognizing that a normal EF at rest lies predominantly within this range is essential for understanding cardiovascular function.
