Key result

ST-elevation in III and aVF with V2-V6 depression may indicate mid-LAD infarction given a prominent ramus intermedius.

Key Points

This research aims to highlight the significance of unique ECG patterns in diagnosing mid-left anterior descending artery occlusions.
Case analysis of a 52-year-old patient presenting with acute angina.
Electrocardiogram findings were documented and analyzed.
Emergent angiography was performed to assess arterial occlusion.
ECG showed significant ST-elevation and depression indicating myocardial infarction.
Angiography confirmed critical occlusion in the mid-left anterior descending artery.
ST-elevation patterns were linked to vector shifts from the ramus intermedius artery.

Structured PICO

Population

A 52-year-old dyslipidemic gentleman with no previous cardiovascular symptoms presenting with acute typical angina for 4 hours.

Intervention

Emergent angiography

Outcome

Angiographic findings (identification of culprit lesion)

An unusual ECG pattern of ST-elevation in leads III and aVF with upsloping ST-segment depression in V2-V6 can indicate a mid-LAD occlusion in patients with specific coronary anatomy.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Should not yet change STEMI triage; hypothesis-generating for ECG variants in prominent ramus intermedius anatomy.
