The passive activates when Karthus is slain ('you have been slain' message)

Any effect that prevents death will be activated before the passive, since Kathus will not be slain.

This includes GA and Zilean's ult.

I am just not sure what happens if you have Yorick's ult on you, because technically you will be dead.
