I'm very scared because I received had an ecg at the doctors office and it said "Normal sinus rhythm Possible Inferior infarct, age undetermined Abnormal ECG"? I'm 39 and never had cardiac symptoms. I haven't slept for days now. chest X-ray and Blood Work were OK. I hike, ski and am generally active. I have severe anxiety hence why i'm asking a random person I found on med help this question. Should I post this question public? I was planning on doing so.
