Is atrial fibrillation a disability?

It can be: If afib is difficult to treat ie unable to convert patient to normal rythm or unable to slow rate down with medicines, or perhapse the patient can't tolerate the medications to treat the problem , a person can be disabled. Pts with pre existing heart problems may not tolerate afib as well. Ablation therapy is not always effective and some patients may need a pacemaker. Just depends on pt

Usually not...but: Most patients with atrial fibrillation can still work. How ever it may get difficult to function normally if you get heart failure, very fast heart rates, cannot tolerate the medicines. Blood thinners used in treatment for atrial fibrillation may also be a problem for people whose work involves a lot of trauma/injury because of the risk of bleeding.

Depends: It depends on the disability resulting from its symptoms. many patients of who have it report no symptoms at all. Older patient with other structural heart disease like heart failure tend to be affected the most.
