Obviously, we can only share our experiences and thoughts and cannot render online an diagnosis. I can tell you that I had considerable anxiety once I started down the path of lots of testing, doctor appointments, etc. That anxiety manifested itself in physical symptoms that were similar to symptoms that I expected to feel from the stenosis. . rapid heartbeat, waking up at night with my heart pounding, light headed, etc. While some of these may have been influenced by the stenosis, I now am confident they were primarily driven by anxiety.
Distraction was the best medicine for me. While internet research and on line groups like this are super helpful, it also helped me to do something else. I was also always comforted when I walked out of an appointment with my cardio. Not because there was any new great news, but I was confident that he wasn't going to let me walk out after a echo or whatever, if there was some imminent risk. I don't know if it was reasonable for me to make that inference but I did and it helped. You had a battery of tests run. I think if they thought something bad was about to happen, they would have done something more than schedule some additional tests a week or so from now.
