i am 29 years old, i weight 308 at 5 9 . i have gerd , high blood pressure and anxiety . i have had slight upper back pain , some neck pain , and a burning sensation on my left shoulder, kind of on back side. all pain is in and out and not always at the same time. i had a stress test done, ekg multiple times, heart monitor on, and ultra sound done. all was clear except the heart moniter. Doctor said for 3 seconds i had a rapid heart beat at night. i was told my heart is fine and that i just have panic attacks and anxiety. so i was given meds for bothe. some time i have heavy heart beats and every once in a while i have my heart feel like it just fliped. does this mean i am about to have a heart attack? or i am having one? or is it just my gerd and anxiety? if all that came back clear, does that mean i am clear of heart attacks if the test were good?
