I was diagnosed with PAF a couple of years ago and had a pacemaker fitted. Am on Bisoprolol and Warfarin. What has me puzzled is what triggers an epsiode. Have looked on the Internet, NHS and AFA websites, but have not been able to find anything. I drink very little alcohol now and for well over half of recent episodes I had not had a drink within the previous 36 hours. I don't smoke and don't drink a lot of tea or coffee, so can anyone suggest anything else I should avoid?
