Inferior Infarct

I just had my yearly physical, I'm 39 years old 5ft 7" tall and 250lb. I don't remember ever before having an EKG, but I had one done this morning and it showed "Possible Inferior Infarct / age undetermined" and the doctor scheduled me for a stress test.
I would like to know what "Possible Inferior Infarct / age undetermined" means and what should I do about it.
I had my gall bladder removed in August, 2004 and a co-worker said I should have an EKG done at that time. If I did there were no mentions of a "Possible Inferior Infarct / age undetermined" at the time.
Thanks

The ECG may not accurately diagnose a prior infarct as some large people can have left axis deviation on the ECG  as a result of a large abdomen and this can mimic an infarct (inferior) on the ECG.  You should have a stress echocardiogram which will tell if you have had a prior MI.
