A member asked:
Had an echo, ef was 76% and 69%. why 2 different percentages? is it physically possible possible to have a 90-100% ef? also cardiolite stress norm.
A doctor has provided 1 answer
EF: The ejection fraction calculated from echo is not exact and is at least plus or minus 10%. As such there is no real difference between the two numbers you quote. A 90 to 100% ef is improbable.
