Kathryn,
Thanks for your question.
I suggest you go to the emergency room as soon as possible for an evaluation. Chest pain that occurs in a patient with a known abnormal EKG is assumed to be cardiac until proven otherwise. Certainly, more information is needed to make a determination of the cause, but this would best be done in an emergent setting.
Best wishes and feel better.
Martin Cane, M.D.
