Re: help does normal egk rule out heart problems?
While what you are describing CAN be straight old panic attacks, an EKG alone will tell you what your heart is doing at the time the EKG is going. It will also show an abnormal rhythm, or if there was damage done to the heart. It will not show if there are any blockages, or if there are any valve problems. The blood work and chest x-ray would show if damage has been done to the heart, or if the heart was enlarged. I would feel some reassurance by these testings. A stress test, or stress test/echo might be the next step to rule out anything else, if your not comfortable with your Dr.'s diagnoses of panic attacks.
I have panic/anxiety, and because of that, the Dr's misdiagnosed me for 7 years with my SVT and mvp. It is hard to tell them apart because the heart races in both instances. The xanax should have helped if it was a panic attack, if even for a few hours while you had the xanax in your system.
However, having said that, I also have GERD, and get bad chest pain, (but not arm pain) so I feel your frustration. It could also be IBS, (which again, I get too lol) with some of your descriptions, so I think your Dr.s probably doing the right thing by referring you to a GI specialist, but if you don't feel convinced, always ask for a second opinion. I would suspect this is probably where the problem will be found.
Hang in there, and I hope you feel better, Michelle
