Refractory atrioventricular nodal re-entrant tachycardia: A rare manifestation of acute massive pulmonary embolism
Bibliographic record
Abstract
With a wide array of manifestations ranging from mild dyspnea to fatal cardiogenic shock, acute pulmonary embolism (PE) remains an enigmatic clinical entity.Vivid electrocardiography (ECG) patterns portrayed in different clinical instances of acute PE have always remained an interesting, yet debatable subject since the classic S1Q3T3 pattern on ECG secondary to PE was first described in 1935.Atrial fibrillation, atrial flutter and atrial tachycardia are commonly described supraventricular tachycardias in association with PE; however, there is scant description of PE in the literature presenting as atrioventricular nodal re-entrant tachycardia (AVNRT).The present report describes the clinical course of an elderly woman presenting with refractory typical AVNRT who was subsequently found to have bilateral multilobar acute PE.To the authors' knowledge, the present report is the first to describe a case involving acute PE presenting as hemodynamically unstable AVNRT requiring cardioversion.

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.
