So detection of elevated serum heartenzymes is more important than ECG changes. However, the heartenzymes can only be detected in the serum 5-7 hours after the onset of the myocardial infarction. So especially in the first few hours after the myocardial infarction the ECG can be crucial.


;Significant ST elevation is defined as:
;Significant ST elevation is defined as:
:ST elevation of more than 2mm in two chest leads or more than 1 mmm in two adjacent limb leads
:ST elevation of more than 2mm in two chest leads or more than 1 mmm in two adjacent limb leads
