High-output heart failure occurs when the normally functioning heart
cannot keep up with the dramatically increased demand for blood flow to one or
more organs in the body. Although a number of conditions can cause the
increased demand for blood and oxygen that results in high-output heart
failure, overall, high-output failure is not a common cause of heart failure.
The table below outlines the causes.

How does it cause high-output heart failure?
Blood contains too few oxygen-carrying red blood
Requires the heart to pump more blood each minute to
