In brief: 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.

In brief: 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).
