I have been dealing with the same stuff for over 2 1/2 month, it all started with a wonky ekg in the er that led me to being admitted into the hospital for a day to have a stress test done and ultra sound of the heart. Both came back fine, but since then, I am dealing with severe anxiety , and stress. I been to the er countless times and all times a EKG is ran and comes back fine, along with my blood work. Also even had a x-ray of heart done. I have even visited my hear doc and she said it was all good. But still not feeling good, waking up several days a week with just a biggest racing heart. They say this can be anxiety , but I just don't like the feeling I am having. I just want to get over this hurdle and start feeling better. The cardiologist said they will probably do a heart monitor for a few days along with at CT scan of the heart.
