An ejection fraction is a percentage given that represents the amount of blood in the heart that is pumped out with each contraction. So no one has an ejection fraction of 100% as the heart doesn't fill up with blood and then completely compress before then relaxing again. The heart squeezes and a certain proportion of blood comes out and then it relaxes again. So the typical ejection fraction is around 55% or more.
