How does the heart increase cardiac output?
3 doctors weighed in across 2 answers
Two ways: Either by pumping out more blood with each beat (by squeezing harder) or by beating faster. The output is the heart rate times the stroke volume. (the amount of blood pumped out with each beat).

Thank
Cardiac output: This is a product of stroke volume or cc's of blood per beat times the heart rate so cardiac output increases with either an increase in stroke volume or heart rate or both.
