Question

An ejection fraction of 30% is
A) normal.
B) characteristic of a healthy person who is engaged in aerobic exercise.
C) characteristic of a failing heart.
D) the amount of oxygenated hemoglobin in the blood in the left ventricle.

Accepted Answer

An ejection fraction of 30% is characteristic of a failing heart. Ejection fraction is the percentage of blood pumped out of the left ventricle with each heartbeat, and a normal ejection fraction ranges from 50-75%. A reduced ejection fraction, such as 30%, can indicate heart failure, which occurs when the heart is unable to pump enough blood to meet the body's needs.
