It is common in anxiety,though,I had a problem with my heart in 95 until 96 I was told over and over that it was anxiety,it turned out to be WPWS (WOLFF PARKINSONS WHITE SYNDROME).after being to the hospital by ambulance and advanced life support many many times and having my heart stopped 10 times in one ride then flown out,I finally was diagnosed with WPWS.It is not easily picked up on EKG.If it was I would not have suffered for a year and a half,just a suggestion to bring up WPWS to your doctor,or maybe look it up on the internet,it is very hard to get a diagnosis for it.
Yes, its common with anxiety. I would see a doctor and just rule other things out. I had the same problems a few years ago and it came down to be anxiety....
