Post myocardial infarction ECG wave tracings

Various phases can be seen through ECG wave tracings following a heart attack:

Hyperacute phase begins immediately after a heart attack
Fully evolved phase starts a few hours to days after a heart attack
Resolution phase appears a few weeks after a heart attack
Stabilized chronic phase is the last phase and typically has permanent pathological changes compared to a normal ECG tracing
