I have had A Fibb on and off for 4 yrs but this year had 6 episodes lasting up to 36hrs between April and the end of Sept. Got to see an EP and he put me on Flecinide 100mgs twice a day. I had been on Bisoprolol 5mgs a day to help with both A Fibb and High B/P. I found Bisprolol had a terrible effect on me over the year I was on it. Depression, exaustion, an irritating cough, weight gain. So I was taken off that. My B/P is now up at times according to 24hr monitor and I was put on Ramipril 2.5mgs last week which I had to stop as I was soooo dizzy I thought I would collapse. My feeling is that these Angio tensins or ACE inhibitors which actually suppress your adrenals don't suit me but my EP says these are the best ones to take when you have A Fibb. Is there anyone out there who is taking a differant kind of Anti hypertensive? like a calcium blocker or a diuretic or a vaso dilator?? and does anyone know why the adrenal suppressors are supposed to be best? I need to understand this and can't get an explanation. My doctor behaved like I shouldn't even ask the question. I was a nurse in the past so I have some knowledge and I guess that's why I want to fully understand how medication works. I am very aware also that my Adrenals are not the strongest as I have episodes of ME type symptoms in the past and have also been diagnosed with Fibromylagia in the past with all that entails...joint pain tiredness and headaches. I'd be grateful for any help anyone can give me. Thank you.
