I was diagnosed with A-Flutter (A-Fib's low rent cousin, though I can tell you that after a week in the hospital plus a planned overnight return plus sleep study and everything else there was a whole lot of "RENT" my insurance did not cover.. Oh for the old days when they covered it).
Though they had me on rat poison when I was in hospital and they were testing every period of time (Multiple times a day) They switched me to Xalarto when I checked out.. There are a couple of alternatives to Coumadin now days... You might wish to speak to your cardiologist.. one of the things I talked to him about is the fact that I'm a full time RVer so weekly visits to the lab are not all that easy to arrainge (Actually they are Great hospital less than a mile from where I go for choir practice every week, but that only applies to my winter-quarters).
I was thinking "I need to talk to him about these alternate meds" and then I checked my list of 'scripts and decided that talk was not needed.
Walked into ER with A-Fib, Congestive heart failure and 20% heart function..
Week later wheeled out and went home, came back a few days later for one procedure.. Weak as a new born over the weekend.. Came back a couple weeks later to be fitted for a monitor, and later to chat with doctor.
On those two fittings due to the Wi-Fi in the park I drove up early in the AM, checked into the hospital (Cafeteria that is) for Breakfast, Lunch and Wi-Fi,, When the place got overly busy and they needed my table, I checked out and hiked roughly a half mile to the doctors (Was nice weather, not too cold or hot, not too windy and no rain, liquid or powder type I enjoyed the walk).
I must say Doctor was impressed.
They put me on assorted diuretics,, I lost over 40 pounds in one week, alas, gained about half back (they cut one diuretic) I will have to talk to him about that when I get back "home". Home,,, is where I park it, "Home" is S.E. Michigan.
