I was diagnosed almost 2 years ago after a very bad chest infection, which triggered a racing irregular heart beat. I was prescribed warfarin to prevent the clotting that AF can cause, also a beta blocker to slow the heart rate. It took months to recover from the chest infection, previously I'd done a three mile walk every morning but until several weeks later, I was lucky to manage half a mile. If an uphill slope was involved, I'd to stop to get my breath back.
I had a cardioversion several months later, it worked and was wonderful but within about 4months, the AF was back. I have low blood pressure and that combined with the AF and beta blocker slowed me down too much, hills were such a strain. The cardiologist took me off the beta blocker and I've felt less tired subsequently.
I was reviewed by the cardiologist this week. Cardioversion is usually successful but about 50% flip back into AF. There are other drugs to help control AF but the possible side effects sounded grim, in addition I take various significant medication for RA. There is another more invasion treatment, I think its ablation. Alternatively a pace maker but the cardiologist said that would leave the heart dependent on the pace maker. He said we could just continue with the warfarin, review me in 6 months and that the long term outcomes for people with AF but no other heart problems, who go without treatment (other than warfarin) is not significantly different than those who elect for more invasive treatments.
I do walk, I have dogs so I have to get out twice a day, which I think has helped me. I asked him about swimming, yes he said, that would help with increasing fitness levels. He confirmed hill walking isn't something I'll enjoy these days.
I asked him about flight socks for long haul, he smiled and said I needn't worry about that because of the warfarin.
Hope this helps Badenkate. It's tedious isn't it.
