Abstract
La implementacion de la prueba de mesa basculante en el ano 1986 para el diagnostico de pacientes con sincope recurrente de origen no aclarado, determino al sincope neurocardiogenico como una de las causas mas prevalentes de disfuncion autonomica cardiovascular. A pesar de su importancia en terminos de salud publica, la fi siopatologia del sincope neurocardiogenico no ha sido completamente aclarada, dificultando asi la implementacion de un enfoque terapeutico apropiado. El reflejo de Bezold-Jarisch propuesto inicialmente como mecanismo causante del sincope neurocardiogenico ha sido recientemente desvirtuado y actualmente se ha sugerido que la etiologia del sincope neurocardiogenico puede estar relacionada con alteraciones hormonales y en la neurotransmison derivadas del sistema nervioso central. Multiples mecanismos han sido postulados involucrando alteraciones en vias nerviosas centrales y perifericas que llevan a hipotension y bradicardia subitas relacionadas con una inhibicion del infl ujo simpatico. Recientemente se ha postulado que la alteracion del sistema central serotoninergico podria ser un elemento clave en la fisiopatologia del sincope neurocardiogenico. En este papel se revisan algunos aspectos del rol del sistema central serotoninergico en la regulacion de la funcion cardiovascular, presentando datos que sugieren su potencial participacion en el sincope neurocardiogenico

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 it
