Hi Godchaser:
I also have the skipped beats and sometimes chest/arm pain. I was checked out 5 years ago with echo, stress test and they said tests were normal. I too have extreme anxiety. Just to be on the safe side you should get checked by dr. but i know alot of people with anxiety get the chest pains and the palpitations. It can be from alot of different things. Heartburn/gerd, muscle spasms ect. I know how scary these things can be. im scared all the time even tho logically i know i have anxiety which stirs these things up. Last couple of months my heart has been skipping and jumping quite alot. And with that i have had recuring pain in left arm/shoulder. So its been a stressful 2 months. Hope this helps knowing others feel as you do. But just for your peace of mind get a doctor to check you out. That always helps me
