Insights
Identifying left main coronary artery occlusion is crucial for prompt treatment. This case highlights how ST-segment elevation in lead aVR can indicate this critical condition, guiding early management decisions.
Area of Science:
- Cardiology
- Emergency Medicine
- Diagnostic Electrocardiography
Background:
- Accurate diagnosis of coronary artery obstruction patterns is vital for timely patient management.
- Left main coronary artery occlusion is a critical condition requiring immediate intervention.
- Electrocardiogram (ECG) interpretation plays a key role in diagnosing myocardial infarction.
Observation:
- A specific ST-segment elevation pattern was observed in a single lead (aVR) on the ECG.
- This ECG finding was associated with an acute left main coronary artery occlusion.
Findings:
- Single-lead ST-segment elevation in aVR can be a specific indicator of acute left main coronary artery occlusion.
- This diagnostic clue aids in differentiating critical coronary events.
Implications:
- Early identification of left main occlusion via aVR ST-segment elevation can expedite treatment strategies.
- This finding emphasizes the importance of detailed ECG analysis in emergency cardiology.
- Recognition of this pattern may improve outcomes for patients with acute coronary syndromes.
Abstract:
Discriminating among the various coronary obstruction patterns influences early management decisions. One of the most important tasks is the identification of ST-elevation myocardial infarction caused by left main occlusion. We present a case of single-lead ST-segment elevation in aVR caused by acute left main coronary artery occlusion.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
