Atrial fibrillation</a> is a fast heart rate(120 to 150 bpm) and the top part of the heart (atria) is beating really fast due to some kind of wiring problem. The right atrium houses the "pacemaker" SA node and it is here generally that the wiring problem is situated. RFA simply uses sound waves to cause scar tissue to parts of the node to correct to calm it down.
I work in a busy emerg and I have looked after several patients that have undergone this procedure all report no real side effects and in one case the ablation had to be done a few times.
Hope this helps
