Vasculitis Presenting with Ventricular Tachycardia
Bibliographic record
Abstract
To the Editor: A 19-year-old female college student presented to the emergency room with sudden onset of palpitations while watching a movie. Her history was unremarkable, and she denied any abuse of alcohol, recreational drugs, or over-the-counter stimulants. Review of systems was negative for any recent fever, rash, sick contacts, or acute illness involving the respiratory or gastrointestinal tract. Vital signs on presentation were notable for a temperature of 100.1°F, a regular tachycardia at 220 beats per minute, and blood pressure 120/70 mm Hg. The remainder of the examination and a chest radiograph were unremarkable. The electrocardiogram showed a wide complex tachycardia with monophasic right bundle branch morphology in lead V1 and right inferior QRS axis (Figure 1). Intravenous procainamide was administered, with prompt restoration of sinus rhythm. The sinus rhythm electrocardiogram was normal. Transthoracic echocardiography revealed normal left ventricular function, homogeneous enlargement of the anterolateral papillary muscle, and mild mitral regurgitation (Figure 2). Differential diagnosis included a cardiac tumor, unusual isolated papillary muscle hypertrophy, or an infiltrative systemic process, … Address correspondence to Dr. A.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
