Family practice : If you have any cardiac risk factors ie smoking hx, hypertension , diabetes, high cholesterol, family hx for heart dz, along with having chest pain it may mean something should be investigated. However you are young and sometimes ekg's read very sensitive results. Static or movements are picked up as abnormal readings. Each ekg needs to be interpretated by a physician. Discuss with your dr.

EKG: It is possible that you had a "silent" heart attack. Additional tests looking at the blood flow to regions of the heart would be needed to tell for sure.

EKG change: Q waves on an ekg suggest prior damage. If there were symptoms, enzyme elevations helps confirm the timing and degree. Compare with any prior ekg. Continue your risk reduction approach, but discuss with your pcp.
