Well its now 6 days since my 9 hour stay in Resus at Torbay hospital where I went unaware I had influenza A and secondly no idea I was in A FIB.. . After 10 mg of bisoprolol my heart returned to normal sinus rhythm.. I was released with 2.5 mg bisoprolol tabs to take as and when which I had one on Friday night as felt funny.. Touch wood now 5 days since really attack but I have no doubt my rhythm is erratic. Still getting over the flu so fingers crossed. So pleased to have found this sight.. I imagine I will be a regular as coupled with my general anxiety disorder I will be battling my fears.. It is great to hear such positive outcomes and I know the road ahead will be up and down.. It's called Life.
