What is catheter ablation therapy?
This can be used to correct fast arrhythmias. Under x-ray guidance one or more fine tubes ( electrode catheters) are fed into a vein and/or artery usually from the groin area. When the area of the heart which is causing the problem is found, the ablation catheter is placed near it.. The catheter tip emits radio frequency energy which destroys the affected areas which causes scarring, which prevents any further electric signals being emitted. It takes up to 3 hours and is normally not painful although you will need to stay in hospital for a short time afterwards. Depending on how many electrical pathways needed to be destroyed, you may also need to have a pacemaker fitted.
