Healing seems different depending on which side of the Force you use. I can't recall where, but the Jedi healing I've seen is basically instantaneous...they heal themselves, and they stay healed without concentrating on it.
In the novel Shadow of the Empire, Vader is trying to heal himself in his chamber. He has to actively concentrate on doing so, and when his concentration fades, his healing is undone.
Also, Horus didn't list it, but Sith can sever themselves from the Force at will. Darth Maul does this in Darth Maul: Shadow Hunter to avoid detection by a Jedi.
