Answers:
I think you probably mean "20% Ejection fraction"...
Ejection fraction is the percentage of blood your heart pumps out in each beat. Even in a healthy patient, the heart doesn't empty completely with each contraction. A healthy person will pump out about 60% of blood with each beat. Your heart only pumps out 20% of its blood volume with each beat. That is a pretty low number. But then again, some people compensate better than others- their vessels squeeze down so that they are able to maintain their blood pressure even though they are not pumping blood as fast as a healthy person.
