First off long time anxiety attacks and panic, So yesterday was feeling heart racing, lasted for a while went to local firehouse, they did a 12 lead rythms looked perfect, but advised me to go to hospital because machine showed possible MI.. Went to hospital, did all the test incl. Heart enzyme and protein test. All came back normal they release me. Today.. I feel very anxious feeling pain, either real or imagined up pain. What's the chances something is wrong or is this just another case of anxiet? Thanks
