title: Ask the Doctor: Because I had a lot of rhythm abnormalities after my heart attack a few years ago, my doctor gave me an implantable defibrillator. I've gotten so used to it that I forgot I even had it until a few weeks ago when I was sitting at dinner and felt a big thump in my chest that nearly knocked me out of my chair. I went to my cardiologist, who did some tests and told me not to worry about it. As I see it, I just died and was rescued by this thing. Shouldn't something more be done for me?
