Advanced interatrial block: a well-defined electrocardiographic pattern with clinical arrhythmological implications
Bibliographic record
Abstract
We read with interest Hinojar et al .1 case recently published in the journal. Their case wisely demonstrated the presence of P-wave with +/− morphology in leads II, III, and aVF as a pattern of advanced interatrial block (IAB). This pattern has been also called ‘block in the Bachmann bundle zone’ since Waldo obtained this electrocardiogram (ECG) pattern by cutting the Bachmann bundle at both sides of the septum [right and left atrium (LA)].2 The electroanatomical mapping (CARTO) showed by Hinojar et al. in sinus rhythm clearly shows that the atrial activation starts normally, but its propagation is blocked along the LA roof and the high lateral activation is delayed and directed caudocraneally starting at the posteroinferior LA region. Therefore, this type of atrial activation …

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.
