Thank you all so much for your responses which have given me so much support. AF is a very scary place indeed. I would have like to reply to all individually but I'm not sure if that is the correct way to go about things, so I hope another post is acceptable.
Warfarin was mentioned by my GP but he says on the CHAD scoring, I was at 1 to 2. As the guidelines were updated only a few weeks ago and I score a 1 for being female and then another for my BP problems. So he's not going to consider the Warfarin at the moment. But he did mention cardioversion if the heart rate continued as it is.
I certainly agree about the lifestyle changes and was told many years ago by my cardiologist that Aspartame should be avoided at all cost, which I have tried to do; but its in everything! I used to really enjoy a diet Pepsi (with Aspartame) and haven't had one for years. Now I wonder should I just bite the bullet and enjoy it regardless, the AF came back without it; (am I thinking a little rationally here? I'm almost excited about having a diet Pepsi!!)
I once had a small episode of AF whilst taking antihistamines. The GP at the time said it was possible that these were the cause and made a note on my record. I was recently prescribed Nasonex for a sinus problem; and upon checking in detail (on a forum), I found that many people had suffered AF type symptoms whilst using this spray, which is a steroid. There is quite a comprehensive list of side effects, none of which are noted in the enclosed leaflet. I mentioned this to my GP and he was most surprised and told me I shouldn't believe everything I read on forums! If there is a link, then I should be informed of all the risks, not just the ones on the leaflet. I have since stopped using the Nasonex and am bunged up as a result,; but rather that than it contributing to this AF.
I am still breathless on the smallest exertion, but not so aware of my heart beating. Maybe things are slowing down?
I have an appointment with my GP next week and will certainly ask for an anti arrhythmia drug. He told me last week that it was too late to prescribe Flecainide. Is there anything else he could give me do you think? Failing this, I shall ask for a referral.
Thank you all.
