atrial fibrillation
"I have been taking 190mg Betaloc for a few years and the main problem is the fatigue that I get . I have perm A/Fib from a failed Maze treatment while having my Aorta valve replaced 9 years ago , I asked my GP if I could lower the dose to  142.5mg daily . I have been doing this now for about 3 weeks but now I am having strong bouts of A/Fib so I have decided to go back on to 190mg again . What are your thoughts on this matter."
