After a diagnostic EPS, what we are then doing is if we identify that you have a heart rhythm problem, typically a fast heart rhythm disorder, we have a technique that we call catheter based mapping. We have a special catheter that has the ability to roam in the heart where we manipulate to different spots in the heart to try and localize the abnormality to a very small area. Once we identify that abnormality, we then can use ablation technology for curative and definitive treatment.
