jtm297, Welcome to HealingWell!!
Hi jtm, I'm glad you decided to stop by and visit with us and I will try my best to give you the best answers that I can! We're not Doctors, so our responses to you are our own.
Your EP Dr. sounds like he's been right on so far with all that he's done! If you have these types of questions, I would strongly recommend that you ask him, or perhaps get a 2nd opinion. That is after all, what they are there for...I'm going to try and find a couple of links for you to read and see if this helps you to understand your condition better.
Please take care and come on back and keep in touch with us and let me know what happens and what you and your Dr. decide on!! I'd really like to know! It sounds like you've been through an awful lot already.
Hugs, Teri
