In Uworld theres a question on diastolic heart failure and it says diastolic heart failure decreases outward ventricular elastic recoil but it also decreases ventricular compliance. I thought recoil and compliance were opposites? or is this just in the lung?

Can someone please explain?
Thanks!

Click to expand...

Recoil and compliance are not opposite concepts. Think of it this way: if the wall of the ventricle is stiffer than normal, it won't expand normally to accommodate the blood. If it doesn't expand normally, how could it recoil normally as well?
