La invención de la onda T del electrocardiograma aplicada a la valoración de las preparaciones digitálicas
Bibliographic record
Abstract
Ja es conegut des de fa temps el fet de la inversib de l'onda T de l'electrocardiograma mitjancant l'administracio per os o per via endovenosa dels glucosids digitalics, encara que els primers investigadors no l'observaren o no li donaren la importancia que mes tard se li ha concedit (Z).Un de nosaltres (Bellido), en utilitzar, en un treball en col-laboracio amb Pi Suiier (2), la digitalina com a toxic provocador de sistoles ventriculars retrogrades, no va observar tampoc la negativacio de la T, la qual ha d'esser atribuida al fet d'haver-se utilitzat dosis altes de glucosid que immediatament feien passar l'animal al periode d'intoxicacio.Cohn (3) va descriure l'aplanament de T i la seva negativacio com a consequencia de l'administracio de digital; aquesta observacio fou confirmada per altres autors americans.Eggleston i Wyckoff (4) observaren, en subjectes malalts que havien rebut dosis elevades de digital, un augment de l'interval P -R de 1'electrocardiograma i negativacio de l'onda T. Es feren identiques observa-

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.
