Atrial Fibrillation

Atrial fibrillation occurs when the two small upper chambers of the heart (the atria) quiver instead of beating correctly. Blood may pool and clot in them instead. If a piece of a blood clot leaves the atria and becomes lodged in an artery in the brain, a stroke is the result.

Atrial fibrillation can be treated with medication, electrical cardioversion, IV medication, radiofrequency ablation, surgery or atrial pacemakers.
