hi, I am a 65 yr old female and have been on Flecainide for one year 150 mg. for heart Palps and 1 incidence of lone AFib, The last two weeks I have been experiencing breathing difficulties and some heart palps, My cardiologist said I could take a Flecainide holiday, Im so apprehensive about it that its causing a lot of stress/ Would love a second opinion, I was told I don t have heart disease, but I do stress over Heart Palpations? Thank you
