An incidental case of Wellens' syndrome in a community emergency department
Bibliographic record
Abstract
Wellens’ syndrome, also called left anterior descending (LAD) coronary T-wave syndrome, is a characteristic electrocardiographic (ECG) pattern suggestive of coronary artery disease in the preinfarction stage.[1–3] ECG changes in Wellens’ syndrome may signify critical stenosis in the proximal LAD coronary artery.[1–5] Furthermore, ECG changes may occur during a pain-free period with no other evidence of ischemia or unstable angina and none to minimal elevation of cardiac enzyme levels.[3,5] Hence, recognition of the aforementioned pattern is important in preventing the development of a devastating anterior wall myocardial infarction.[2–5] There are two patterns of ECG changes related to Wellens’ syndrome. The first involves a minimally elevated or isoelectric ST segment with inverted T waves in leads V2 and V3, often in leads V1 and V4, and occasionally in leads V5 and V6.[1–3,5] This pattern accounts for approximately 75% of Wellens’ syndrome cases.[3,5] The second pattern involves biphasic T waves in leads V2 and V3[1–3,5] and accounts for roughly 25% of Wellens’ syndrome cases.[3,5]

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
