I left it drying on the radiator overnight. How bad is that?

Did something stupid last night. Washed a latex top, could not be bothered to wait for it to air dry properly because I want to wear it on Friday, and draped it over the radiator in the spare room before bed. The heating was on a timer so it was warm for a few hours.

This morning it is completely dry and it looks, as far as I can tell, fine. But everything I have read since says heat is one of the worst things for latex, so now I am waiting for it to fall apart.

Is it ruined and I just cannot see it yet? Is there anything I should check for? And is there any way of drying something quickly that is not this.
