What is the normal range for EF?

Explanation:
A normal EF reflects good left ventricular systolic function, indicating how much blood the ventricle pumps out with each heartbeat. In most medical references, normal EF sits in roughly the 50–70% range, with many educators using 55–70% as a standard window. The range shown here that best aligns with that normal band is 60–70%, because it sits comfortably within the accepted normal values and avoids the lower end where dysfunction becomes more likely. Values well below this range (for example, around 40% or lower) point toward systolic impairment, while very high values can occur in hyperdynamic states but are not needed to define normal.
