I have a modest case of AFib..I say modest because diagnosed in 2015..full echo resulted in normal status and has been the same with a new"full checkup last month". The only issue was
an enlarged atrium which is an offshoot of Afib. Enlarged atrium is common, but can also be a result of activities, weight, strength, exercise etc. As a former US Army Infantry officer, I suspect perhaps the enlargement could be a result of several causes.

I use the VA clinic in Viera/Melbourne, Florida as a second opinion to my normal doc who I see
just once per year. Frankly, the VA is absolutely outstanding..But, here is the point of this rambling...the nurse I spoke with yesterday worked at the Mayo Clinic in Jacksonville. She could not find the words to say how excellent the facility was in every way. She moved south to be with extended family as she is about 6 months pregnant. This comment reinforces
the comment before mine. The lesson is: If available, make every effort to go to the best there is in terms of health care; seek second opinion; use the net and forums like this to inform yourself of options. (I do take Padaxa as blood thinner and atenolol as beta blocker and also lowers blood pressure. Cheers All/RH
