“Ablation is removal of material from the surface of an object by vaporization, chipping, or other erosive processes. Cardiac ablation is a procedure that can correct heart rhythm problems (arrhythmias).Cardiac ablation works by scarring or destroying tissue in your heart that triggers or sustains an abnormal heart rhythm. In some cases, cardiac ablation prevents abnormal electrical signals from entering your heart and, thus, stops the arrhythmia.”
