When examining the electrocardiogram, look at how the injury current distorts the second portion of the QRS for an important prognostic sign (American Heart Journal).
In anterior infarction does the S wave in V2 and V3 fail to dip below the isoelectric line? In inferior infarction is the ST takeoff (J point) greater than half way up the height of the R wave? These electrocardiographic findings indicate a worse outcome, in particular poor results from reperfusion efforts via systemic thrombolysis or catheter intervention.
