Do I need to be on anticoagulants. My consultant says I no longer have A/F after ablation but I do have regular ectopics, which increase with increased exertion. I had an episode two years ago where I momentarily could not finish my words, very brief, this was followed by a headache. I had all the usual tests nothing abnormal found and conclusion was it could have been a TIA or migrainous. Since then have been on warfarin converting to rivaraxoban. I am also on Bisoprolol 2.5 mg.
