Atrial fib wtf plus mrsa

Ok since 2004 I have had intermittent bouts with atrial fib. My heart is rapid irregular and weak.  It makes my head hurt and I can't exert myself at all. I used to go to the ER and they would try medication , it never worked, then they would admit me, monitor me and schedule a cardio version. I would always convert to normal sinus rhythm before the cardioversion. I got sick of going to the ER so I now live in a anticoagulated state on Coumadin and have short acting antiarrythmic medication that I take every four hours until I convert. There is a surgical option but my wt precludes the surgery.
 In light of my scheduled wls I am thinking about this on two levels
one that I will have an episode before during or after surgery and
two that achieving wt loss will allow me to have  the surgery to put a stop to theses debilitating episodes.
 Unfortunately in the past week I have had the first episode in over a year lasting over 24 hours and then another episode also lasting 24 hours. So my concern about it interfering with my wls is very real. Also I had to use 12 hours of paid time off on friday and I need every hour for my time off for surgery.

Then there is my MRSA which is meth resistant staph aureous. This infection used to be named a nosocomial or hospital acquired infection but they changed it to MRSA and now it seems to be treated like leprosy. You are labelled for life and isolated whenever you are in the hospital. Which means i get a private room which works for me but it irritates me that I am treated like a leper and the hospital the freaking source of the microorganism is absolved of all blame or responsibility.
