It depends on where you mean in Western NC. Joseph Souza is a respected electrophysiologist that trained at University of Michigan. He works with Asheville Cardiology. If your doctor does ablations, it is probably worth talking to them about it is as well. Most ablation procedure relatively straight forward.

It sounds like you have significant symptoms and probably would benefit from an EP study and possible ablation.
This is a good
patientKidney diet - dialysis patients reference for ablations. It has many useful links and information.

It is on the
patientKidney diet - dialysis patients education portion of the uptodate.com site. The
patientKidney diet - dialysis patients section is free.
Good luck with your procedure.
