Ablation

Catheter ablation is a procedure that very carefully destroys the diseased area of your heart and interrupts abnormal electrical circuits.

It’s an option if medicine has not been effective or tolerated.

Catheters (thin, soft wires) are guided through one of your veins into your heart, where they record electrical activity.

When the source of the abnormality is found, an energy source, such as high-frequency radiowaves that generate heat, is transmitted through one of the catheters to destroy the tissue.

The procedure usually takes 2 to 3 hours, so it may be carried out under general anaesthetic, which means you’re unconscious during the procedure.

You should make a quick recovery after having catheter ablation and be able to carry out most of your normal activities the next day.

But you should not lift anything heavy for 2 weeks, and driving should be avoided for the first 2 days.
