Electrocardiographic Findings in Adolescents With Eating Disorders
Bibliographic record
Abstract
OBJECTIVES: We sought to determine the prevalence and clinical correlates of electrocardiographic findings in adolescents with eating disorders. STUDY DESIGN: We undertook matched case-control study of electrocardiographic findings at initial assessment in 62 adolescents with anorexia nervosa, 9 with bulimia nervosa, and 26 with eating disorder not otherwise specified presenting from March 1995 to September 1996. RESULTS: Mean (+/- 1 standard deviation) age was 15.0 +/- 1.4 years (95% were female). Patients with anorexia nervosa had significantly lower heart rates (mean case-control difference: -20 +/- 17 beats per minute), lower R in V(6) (-2.6 +/- 5.5 mm), longer QRS interval (+.004 +/-.010 seconds), shorter mean QTc (-.0136 +/-.033 seconds) and lesser QTc dispersion (-.010 +/-. 031 seconds). The bulimia nervosa group had slightly longer mean QTc (.019 +/-.020 seconds), with no significant case-control differences in the eating disorder not otherwise specified group. CONCLUSION: Electrocardiographic findings are abnormal in adolescents with anorexia nervosa but not in adolescents with bulimia nervosa or eating disorder not otherwise specified.

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.
