t help anything. It just makes us miserable. You take care
of what you can, let the doctors take care
of what they can, and try to roll with the punches, so to speak. Maybe you will (or won't) need a pacemaker someday, and if that's the hand you're dealt, there's nothing to be gained by worrying about it until that day comes. I'm not sure what your dad's problem is when you say severe exactly, but a pacemaker really is not that big a deal, in the grand scheme of things.
