I had a defibrillator fitted last June, it also encompasses a pace maker. I didn't join any support groups, even though there is one for patients like myself. I find that some people can see problems that don't really exist at all in groups like this, this sometimes leads to worry, etc, for others that doesn't really happen at all. There really is nothing at all for her to worry about, but here's a link if you think it will help. Remember what I said though.
