Postural tachycardia syndrome and coronary artery bridge
Bibliographic record
Abstract
Postural tachycardia syndrome (POTS) is characterized by the presence of orthostatic tachycardia in the absence of orthostatic hypotension with a heart rate increase of >or=30 bpm. Patients often relate complaints of palpitations, exercise intolerance, fatigue and near-syncope or syncope, other non-specific symptoms such as headache and nausea may be present as well to varying degrees. Myocardial bridging is rare occurring in 0.5-16% in angiographic studies. Clinical presentation is protean and can manifest as atrioventricular blockade, ventricular tachycardia, myocardial ischaemia, sudden cardiac death, and myocardial infarction. However, the majority of patients with myocardial bridging are asymptomatic. We describe a case of POTS syndrome and myocardial bridging co-existing and presenting a therapeutic challenge.

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.
