I don't understand Heterometric regulation!

[StrongBeliever]

In my book it says,
Heterometric regulation:

It's characterized by:

• It depends on a different EDV (increased ventricular blood volume at end of diastole, increases CO and vise versa)

Could someone please explain this sentence.

Me either.

The more the muscle fibers are stretched, the harder they recoil. Increase in preload (LVEDV) leads to an increase in cardiac output.
