43 yr old male, 73 inches, 200 lbs. BP 120/76, HR 57. Have had regular EKGs, ECGs, and stress tests the past 5 years or so for physicals and life insurance applications, but today I received an EKG result that says "consider anteroseptal infarct". Doctor asked me if I was an avid runner (I am not) because my EKG indicated an enlarged heart. Should I be concerned about this, or might this be an anomoly?
