Atrial Fibrillation (AFib) Support Group
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spread through the heart and cause contraction of the heart muscle and pumping of blood.

I've only been back on Coumadin for a month and am not stable yet. But it should be no problem. Most doctors I've talked to are avoiding the newer anitcoagulants, like Xarelto because there is no antidote. Coumadin has been around for decades so its action, and termination, is well understood.
I used to think the same way but after going to a rock star ep I felt differently.
As an example to illustrate my point - I was initially diagnosed with afib by routine cardiologist ecg. Cardiologist (who I hold in the highest regard) followed up with numerous tests like the ones you mentioned and since CHADSvasc was 0 prescribed aspirin.
I later went to a rock star ep who did a 7 day holter and although CHADSvasc was 0 recommend anticoagulation based on afib burden. EP was more knowledgeable in studies regarding afib burden and from personal experiences in dealing with afib patients that had similar profiles to mine.
Treating arrhythmias is all this ep does. And when he is not treating patients he is researching them, attending classes and conferences, talking to fellow ep, reading papers etc. It would not surprise me if he dreams about afib. All this translates into better patient care.
I dont think all eps are the same but in my opinion the average ep will have more knowledge and experience than the average cardiologist and that translates into better care.
Other than ablations, elite eps can do cardiac MRIs to assess fibrosis and give you a better sense of ablation outcomes, evaluate left atrial appendage morphology to work out anticoagulation strategies, etc. These are examples other than ablations that unfortunately cardiologists cannot do and may not even be aware of.
My 2 cents
The first EP I saw wasn't interested in doing anything other than ablations, thus my less than stellar attitude. I saw my cardiologist today for a long talk, essentially going over what I said above. She recommended a different EP who she feels is much less inclined to (in my words), go for the knife. I'm going to try this new EP, you've given me some hope that this might be a worthwhile experience.
So, if I had stayed with my reg cardiologist he would have kept me on rate control and I would likely be in permanent afib by now.
I have no doubt that some EPs are only interested in surgery....hope you will find the right one for you.
Those with FACC designation also have attained the Fellow of the American College of Cardiology status. That requires a minimum of ten years of clinical and educational preparation and passing a rigorous two-day exam given by the American Board of Internal Medicine. Most EPs have passed this Cardiology Board exam.
So you get a cardiologist that specializes in heart rhythm problems. They are the most "up" on afib treatments. If heart disease (the plumbing kind) is your problem, see a cardiologist. There are tons of them. If you have afib, why not see an EP? Monitoring fibrosis, left atrial size, ejection fraction, CHA2DS2Vasc, atrial shape, etc... these are the things that EPs know most about.
