@fdixon63 It was not part of my workups. I had chest x-rays, MIBI stress test on a treadmill with contrast and CT scan (X2), MRI, echocardiogram, and an angiogram. These were all to rule out structural abnormalities or defects and to rule out ischemia, which is what my cardiologist thought might have caused my AF.

I did have a TEE (trans-esophageal echocardogram) tube inserted down my esophagus during both catheter ablations. These must be done during GA since 99% of us would balk and fight it while it's being inserted. And catheter ablations are done under GA 99% of the time (very few rare exceptions).
