Asking for bf he is 36 what does ECG sinus rhythm possible septal infarct abnormal ecg. Vr 65 pr 166 qrs 86 qtc 412. Is this anything to worry about?

Not worried. Generally nothing to worry about unless of course he has symptoms. Everything reads normal except for the possible septal infarct bit. That is often related to lead placement issues but is worth discussing with your doc.
Maybe (not) The values of the numbered intervals you provided appear to be normal. With regard to the "possible septal infarct", that means the automated interpretation is that he may have had a heart attack in the past. Although this may be true, you should know that the computer algorithms used for ekg's are designed to avoid missing anything important. So they often over-diagnose to avoid missing things.
