HI, my 70 year old husband has non symptomatic atrial fibrillation. It is quite mild and is constant permanent since February. He tried cardio version and it reverted back immediately. He has a chad score of 0 and is normal weight, B/P 110/70, pulse 60, cholesterol 140. His pulse did not get irregular with the stress test. He is quite active. He was put on xarelto and from what I read, he is not a candidate for that. He wants to hear that from a doctor. The American Heart Association says it is not necessary with no cardiac risk factors. Any ideas on how I can get him to drop this drug.
