Cardiac Output Can Be Increased by All of the Following

Question

Cardiac output can be increased by all of the following except
A) decreasing ejection fraction.
B) decreasing end systolic volume.
C) increasing stroke volume.
D) increasing ejection fraction.
E) increasing heart rate.

Accepted Answer

Decreasing ejection fraction means that less blood is being pumped out with each heartbeat, which would decrease cardiac output. The other choices would all increase cardiac output.
