Having been admitted to hospital from a&e with an irregular and racing heart rate of 150 back in March and told that I most definitely had AF. I am now having another 48 hour holster monitor to try and confirm what I do have! Possibly SVT also. Symptons include breathlessness, palpitations and occasionally fast irregular heartbeat. So I thought I was classic PAF. If the monitor shows nothing, which is likely, then I am to be fitted with an implanted loop recorder. All this before we decide on an ablation.... Goes on and on... Anyone else had this kind of experience. Also coming off warfarin due to constant headache, will be starting Dabigatran next week.
