“Cardiac ablation is a treatment for irregular heartbeats, called arrhythmias. It uses heat or cold energy to create tiny scars in the heart. The scars block faulty heart signals and restore a typical heartbeat.

Cardiac ablation is most often done using thin, flexible tubes called catheters that are inserted through a blood vessel. Less commonly, ablation is done during heart surgery.

Cardiac ablation is a treatment to stop or prevent irregular heartbeats, called arrhythmias.

An arrhythmia happens when the electrical signals that tell the heart to beat don’t work as they should. The heart may beat too fast or too slow. Or the pattern of the heartbeat may be irregular.

Depending on the type of irregular heartbeat, cardiac ablation may be one of the first treatments. Other times, it’s done when medicines or other treatments don’t work.”
