Heart ablation is a procedure used to treat rhythm problems, called arrhythmias. Ablation destroys abnormal heart tissue that is causing the arrhythmia.
During the procedure, a special ablation catheter is placed near the abnormal tissue. A tip on the ablation catheter sends electrical signals, heat, or freezing to destroy the abnormal tissue, and leaves a scar. Scar tissue cannot send electrical signals that cause an arrhythmia.
