title: Ask the doctors. I recently developed atrial fibrillation, and I wonder whether I need to take an anticoagulant. I am 81 years old, active, and don't really notice when I am in atrial fibrillation. I was taking my pulse every now and then and found it to be irregular. My doctor said I was going back and forth between normal heart rhythm and atrial fibrillation. I am in normal (sinus) rhythm now, but he says I should be on warfarin because I have high blood pressure. What do you think?
