P6646Real life EP lab without fluoroscopy
Bibliographic record
Abstract
Background: Arrhythmias' invasive treatment requires X-rays to introduce and guide catheters to target ablation foci. X-rays have no therapeutic role in patients (pts) and there is no clear safe exposure dose either for pts or for EP physicians. Purpose: Single center experience with a daily life fluoroscopy free EP lab to guide introduction, navigation, mapping and ablation catheters in the four chambers of the heart. Methods: A near zero EP program was started in 2009, using 3-D mapping technology,beginning with flutter ablations FLU, AVNRT, AVRT, and finally complex AT and VT ablations; fluoroscopy elimination was achieved early in the experience, even pregnant patients were safely offered EP procedures when needed. Duration was measured since pts arrival to departure from EP lab. Acute success needed arrhythmia or substrate elimination with no complication. EPS were pts with palpitations in whom no arrhythmia was found. Follow up was completed in 81% of this cohort (1–61 months).

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.
