Ventricular Pre‐excitation
Bibliographic record
Abstract
The term “ventricular pre-excitation” implies that the myocardium depolarizes earlier than expected if the stimulus follows the normal pathway through the specific conduction system. In fact, this is not really what happens before excitation (pre-excitation). Instead, it refers to ventricular excitation occurring earlier than expected. Three types of pre-excitation have been defined: Wolff–Parkinson–White pre-excitation (WPW), atypical pre-excitations, and short PR pre-excitation. Patients with WPW pre-excitation can present paroxysmal reentrant tachycardia using an AP (slow–fast type), accounting for 50% of all supraventricular paroxysmal tachycardias. The likelihood that reentrant paroxysmal arrhythmias are generated is lower than in WPW-type pre-excitation. In comparison with WPW-type pre-excitation, fewer cases of reentrant paroxysmal tachyarrhythmias are observed and the risk of sudden death is probably lower, although the occurrence of atrial fibrillation with rapid ventricular response is a potential risk.

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.
