What Is Atrial Fibrillation?

Author/s: 
Rebecca Voelker

Atrial fibrillation is an abnormal heart rhythm that can cause stroke, heart failure, heart attack, chronic kidney disease, dementia, and death.

Atrial fibrillation is classified as paroxysmal (intermittent episodes lasting 7 days or less), persistent (lasting more than 7 days), long-standing persistent (lasting more than 1 year), or permanent.1

In the US, atrial fibrillation affects about 10.55 million people and is more common among men than women. Other risk factors include older age, smoking, high blood pressure, diabetes, heart disease, high alcohol consumption, sleep apnea, an overactive thyroid gland, and possibly genetic factors.
