 Atrial fibrillation is an abnormal heart rhythm caused by disorganized electric impulses on the atrial wall.  This causes the heart to beat in a quivering motion rather than an organized, efficient beat.  An effective treatment is ablation surgery, where the abnormal tissue of the atrium is destroyed, typically performed by inserting a catheter and scarring areas of abnormal electric activity.  The ablation procedure scars the tissue, rendering it ineffective in transmitting electric signals.  The reduction in electric activity allows the heart to beat normally.
