I do not have a pacemaker or defibrillator and am hoping this will prevent me from having to have one. Am also hoping I can get off the Disopyramide. That stuff is AWFUL. I've read there is a Rx to help with the dry mouth, nose, eyes but ....who wants to add yet another medicine when I'm anti Rx in the first place. I'm normally even anti doctors but when a 2nd cardiologist read all my reports and said he agreed I decided maybe mine knows what he's talking about ....haha. The second guy also said it looks like it's possible I'll be referred for a sepal myectomy and if I were his patient I'd ONLY be sent to Mayo. When I had a follow up with my doctor and he suggested the surgery and also said Mayo I did feel better. He even said there is a doctor in Boise who said he would do it but he didn't recommend it. Then told me the stats. WOW! I had no idea how few of these are done and totally understand now why places like Mayo and Cleveland are the places to go.
