diagnosed with afib 3 years ago put on flecanide 50 mg for the next 3 years with no recurring afib irregularities. have taken all heart related tests, ecco, mri, catsacan stress test and blood workup to determine if amyloid is the problem. doctor took me off flecanide and put me on a betablocker to help heart functon. i am also on a bloodthinner coumadine, and the results have been satisfactory. my question for you is it possible that the flecanide could have done damage to my heart thereby possibly eliminating the amyloid theory. many thanks, ronald silverman
