How does a 12 second EKG show a prior heart attack? Like, what shows on the waves that represents the heart attack? Curious, not urgent

In brief: Changes

An ekg shows changes in electrical conduction.
That is how it demonstrates heart attacks.

In brief: Text Book

There is no simple answer to that other than an ekg is a standardized way to look at the heart muscle energy and how it is beating.
If the beats are in any stereotypically abnormal this can be interpreted in a number of ways including heart damage caused by infarction.
