Then there's wiki about it https://en.wikipedia.org/wiki/Necrophilia#Classification
Then there's some other sites about it, going about the stages bodies go through after death, with the first and very important being rigor mortis.
She doesn't have rigor mortis. And no other physical changes have been mentioned other than heartbeat or related to it.
So, basically she's sort of a limbo of quasi-death. The main points of argument of whether she's alive or not, would be if you consider that being dead is when the heart stops beating or when the soul is removed (there was someone who had weighed a dying person, and after some time the weight decreased a little, and they assumed that was the soul leaving)
