Ultimately cardiac output can be reduced to very low levels.

The heart will not be able to stretch as far or develop the pressure required to increase the cardiac output.

To maintain cardiac output at reduced pressure, the heart rate must be increased.

A larger heart results in higher cardiac output, as more blood is pumped out with each beat.

Clinical measurement of cardiac output has been available since the 1970s.

The heart may be working well otherwise, but it cannot produce a high enough cardiac output to keep up with this extra need.

The general effect is one of reduced cardiac output and increased strain on the heart.

Such a position is associated with decreased cardiac output in most pregnant women.

Increases in blood sugar, breathing and cardiac output are all required.

Cardiac output is the term that describes the amount of blood your heart pumps each minute.
