Atrial Tachycardias can be treated with an ablation procedure. We need the focus to be firing off on the day for the procedure to be successful.
A catheter is advanced from the leg to the atria. The catheter is used to map the atria to find the earliest site of activity.
Because the rapid focus radiates out like dropping a pebble in a pond, it is a matter of find the site of earliest firing. Heat energy is then delivered to cauterise the small areas of rogue cells.
