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
