Early diagnosis of acute myocardial infarction (AMI) is vital for timely reperfusion therapy. This case highlights the diagnosis and management of a patient with inferior, posterior, and right ventricular ST-elevation myocardial infarction using electrocardiography.

Area of Science:

  • Cardiology
  • Emergency Medicine
  • Diagnostic Imaging

Background:

  • Acute myocardial infarction (AMI) requires prompt diagnosis for effective reperfusion therapy.
  • Electrocardiography (ECG) is a critical tool in diagnosing ST-elevation myocardial infarction (STEMI).
  • Multivessel territory STEMI presents diagnostic and therapeutic challenges.

Observation:

  • A 56-year-old male presented with sudden, severe chest tightness.
  • Initial electrocardiography (ECG) revealed ST-elevation in inferior, posterior, and right ventricular leads.
  • This pattern indicated a complex ST-elevation myocardial infarction (STEMI).

Findings:

  • The patient was diagnosed with inferior, posterior, and right ventricular ST-elevation myocardial infarction (STEMI).

  • ECG interpretation was key to identifying the extent and location of the infarction.
  • Differential diagnosis considered other causes of chest pain and ECG changes.

    • Implications:

    • Accurate and rapid ECG interpretation is essential for guiding reperfusion strategies in STEMI.
    • Understanding complex STEMI patterns improves patient outcomes.
    • This case underscores the importance of a systematic approach to chest pain evaluation in the emergency setting.
