I’ve been diagnosed with atrial fibrillation (AFib). What does that mean?
Atrial Fibrillation (AFib) is a heart rhythm disorder that causes the heart’s two upper chambers (the atria) to beat chaotically and out of coordination with the heart’s two lower chambers (the ventricles). It is the most common heart rhythm disorder and affects approximately 3 million people in the United States.
For someone with AFib, the atria may beat as much as 400-600 times a minute, which is four times faster than a person who does not have a heart rhythm disorder. Although AFib is not immediately life threatening, it can lead to other rhythm disorders, cause fatigue, dizziness, shortness of breath, and increase your risk of congestive heart failure and stroke. In most cases, AFib is a chronic progressive, inflammatory disease, so it is important to get treatment as soon as possible and to follow your treatment plan.
