<s>[INST] I am looking at a ECG recently taken of a family member. I am only an EMT-B, and do not have sufficient ALS-level training in properly interpreting an ECG. At the top of this copy, i see that it says, Sinus Rhythm, Septal Myocardial Infarction, Possible Left Atrial Enlargement and Abnormal ECG. I wasn t the one who my family member to get this done, and I m upset I wasn t told about it. She is a 78y/o Female. Should I be concerned? If requested, I will scan and upload a copy of the actual ECG print [/INST] Hi, The ECG interpretations whicChatDoctores printed on the ECG paper are machine interpretation of the ECG and could be wrong. So I would like to suggest you to upload the ECG image so that I can review it and give my opinion accordingly. Septal myocardial infarction means a patient had a heart attack which has affected the interventricular septum. Hope I have answered your query. Let me know if I can assist you further.  </s>
