What is the normal range for ejection fraction in percentage?

Ejection fraction is a critical measurement used to assess the percentage of blood that is pumped out of the heart's left ventricle with each heartbeat. It is a key indicator of heart function, particularly in diagnosing and managing heart conditions. The normal range for ejection fraction is typically considered to be between 55% and 70%.

Individuals within this range have adequate cardiac output and heart function, reflecting healthy myocardium and effective pumping capability. When the ejection fraction falls below this range, it may indicate underlying cardiovascular issues, such as heart failure or cardiomyopathy, which can lead to symptoms like fatigue, shortness of breath, and fluid retention.

While the other ranges presented may indicate varying levels of heart function, they do not align with the established normal range for ejection fraction, thus the answer that specifies 55-60% accurately reflects a portion of the normal range. However, it is crucial to recognize that 60-70% encompasses the entirety of what is considered normal.
