A case of successfully treated fetal supraventricular tachycardia in the late first trimester
Bibliographic record
Abstract
We present a case of early diagnosed fetal supraventricular tachycardia in the 13 th week of gestation.Fetal supraventricular tachycardia was confirmed at the reference centre with a ventriculo-atrial to atrio-ventricular (VA/AV) interval ratio of 1.06, indicating a form of tachycardia with a borderline VA interval.The ventricular inflows were characterized by monophasic filling without any signs of atrio-ventricular insufficiency.The ductus venosus demonstrated an abnormal velocimetry.Given the severity of the condition of the fetus, the medical team faced the challenge of quickly implementing transplacental therapy and the need to rule out trisomy 13.Therefore, a direct karyotyping was immediately performed.Next, the patient was qualified for amiodarone transplacental therapy.Follow-up scans revealed a reduction in nuchal translucency thickness, no signs of fetal oedema, restoration of sinus rhythm, and a normal flow profile in the ductus venosus.At 18 weeks and 4 days the therapy was terminated.The baby was born at 39 weeks of gestation through natural labour.Neonatal mass was 3840 g, and 10 points were scored on the Apgar scale.No abnormalities were found in ECG and neonatal echocardiography.The definitive cause of late first trimester supraventricular tachycardia in the described case has not been determined.

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.
