I was diagnosed with AF nine years ago and had a pacemaker implanted. Until recently I have been well but the AF is now more frequent and pronounced. I get very feint and had one blackout, which was horrible and frightening! I am taking the blood thinner Rivaroxaban, plus Bisoprolol 1.5 morning and Doxasosin 1mg evening. I have been advised to give up all refined sugar, caffeine, carbs and alcohol and having done all this I am no better. Obviously I have to go back to my doctor but in the meantime does anyone have any views on this they could share with me?
