Atrial fibrillation is the most common type of arrhythmia and occurs when rapid disorganized electrical signals in the heart's upper 2 chambers (atria) causes them to contract very fast and irregularly. This causes blood to pool in the atria and it is not pumped completely into the heart's 2 lower chambers (ventricles). The upper and lower chambers of the heart do not work together as they should.
Treatment may include:
- medication
- electrical cardioversion - a jolt of electricity is delivered to the heart in an attempt to restore normal heart rhythm
- ablation - used to restore a normal heart rhythm when medicines or electrical cardioversion does not work
