atrial fibrillation
Chaotic upper chambers
Atrial fibrillation is a heart rhythm disorder in which the upper chambers of the heart beat irregularly and out of coordination with the lower chambers.
Often shortened to AFib or AF.
The condition increases risk of stroke and heart failure: She was diagnosed with atrial fibrillation after experiencing palpitations.
Episodes may be intermittent or persistent.
