keeping me on that dose, as the software recommended, for the next fortnight, then I have another test. I've had PAF for nearly two years and the last episode was in September when I was kept in hospital overnight for an angiogram ( clear, thankfully.) I really try to follow the warfarin guidelines. Also, recently I had a cholesterol reading of 6.03, so that is being monitored. Does anyone have fluctuating warfarin readings and if so, how do you deal with them?
