[Star Wars] Is it possible for a dark side user to use force lightning to restart someone's heart?

Let's say someone is having a heart attack in the Star Wars universe and a friendly Dark Lord of the Sith (or any strong dark side user) is around. Can he/she restart the persons heart with force lightning? Can the lightning be controlled like a person peeing? Or can you only release it in the full torrent? Can it only be used for pure destruction? Those who use the dark side always boast that it's more powerful, but if it can't be used for anything legitimately helpful then it seems to quite limited. (Sorry for all the questions in one post but I'm a curious guy...)

In Legends, yes - Cade Skywalker does exactly that in the Legacy comic line.

In canon, no.

As for amount released, yes that can be controlled. Palpatine does exactly that with Luke at Endor, starting with just enough to hurt him, but eventually scaling up to where he was going to kill him had Anakin Skywalker not intervened.

The dark side isn't more powerful, but it is more "showy" and destructive.
