Had am ekg today read normal sinus rhythm, septal infarct, abnormal ecg. please explain what's wrong with me...?

Not necessarily: A completely normal ekg would have a small r-wave in one lead (v1); if that r-wave were missing, the ekg would be interpreted as suggesting a septal infarct (heart attack). However, the absence of an r-wave can be seen when a non-infarction process (fibrosis) occurs or it can be seen if one has another conduction abnormality called a left anterior hemiblock. An echocardiogram could clarify this.

Usually a false read: Computerized reading of ecgs are notorious for over-calling "possible septal infarct". This is often due to incorrect positioning of the ECG leads on the chest. I would have a cardiologist look at your ecg, or simply repeat it, with careful attention to proper precordial lead placement.

Check with your doc: I assume you are looking at the computer-generated readout on ekg. You have a normal sinus rhythm meaning heart is beating in a normal manner. The septum refers to the part of the heart in between the two ventricles. I don't usually rely on a readout from the ekg machine itself when i interpret an ekg so check with your doctor before getting worried.
