Abstract

fetched live from OpenAlex

Almost 50 years ago, we published detailed hemodynamic findings in a patient with heart failure and intermittent left bundle branch block. Delayed intraventricular conduction was consistently accompanied by an increased duration of left ventricular (LV) isometric contraction, a drop in systolic blood pressure, a rise in heart rate, and a drop in cardiac output. To our knowledge, this observation provided the first ever evidence that delayed mechanical LV contraction was associated with deterioration, and return to a normal pre-ejection phase with improvement in LV function.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
