Dianna @holly1275 That's a tought one as i didn't handle the Anxiety as well as i probally should have. First I will say I have not had the exact problem you do now that I read about it. I did have thinking of the muscle on the outside bottom which gave me Arrhythmias which is very scary also. I would go into a rythum that would be like a quiver so no blood was flowing and it did cause a lack of oxygen so in some ways similar.

The surgeries I had were done via my arteries in the groin and they would try to stop the bad rhythms by burning the pathways causing them but it was not always easy to find them.
So we got to the point where the ablations weren't working and the meds were not either. For me I finally got to the point where I probally was looking at meeting God a bit earlier
Than expected. I guess I would say having a great team at Mayo Clinic and the potential for Heart Transplant was my saving moment. I was looking forward to something different than what I had been thru and I'll admit I actually was praying for God to take me rather than deal
With this heart that was failing. So when my Doctor i had for the VT which is Ventricular Tachycardia of really fast heart beat suggested being evaluated for Transplant that actually gave me hope. So as also you figured out my faith was a factor also.
So I really hope this helps as you so want to be back to where you were and maybe Heart Transplant can give that to you. I also will put a plug in for Mayo Clinic and they do hundreds if not thousands of Transplants and the team aproach was awesome. I always had my questions answered and support staff like the Social workers for general problems like insurance or things that seem to come up but are not medical in nature, the Chaplins were great and everyone is so eager to help.
Try and stay
Positive that as i like to say when one door is closing then God will open another door and with me that was for sure how it worked out.
