A member asked:

Can you see heart attack changes on a 3 lead ekg?

A doctor has provided 1 answer

Well: I'm electrocardiogram there are usually changes that reflect haven't had a heart attack or myocardial infarction. However electrical abnormalities in the conduction system of the heart can't look like a heart attack or infarct. Also some infarcts do not show up on the EKG. Most the time the EKG is abnormal and shows a prior heart attack or while you're having a heart attack itshows the acute changes of a heart attack but it's not 100%
