Novel Approach to Diagnosis of a Wide‐Complex Tachycardia
Bibliographic record
Abstract
Despite sophisticated atrial and ventricular pacing techniques used during electrophysiologic study, the exact mechanism of some tachycardias remain elusive. In this situation, eliminating conduction from specific tissue and observing the effect on the tachycardia can be diagnostic. Such a maneuver can be performed using the technique of ice mapping, which entails reversible cooling of tissue to test function prior to delivery of a permanent ablation lesion. We present a case of wide-complex tachycardia with inconclusive results from diagnostic electrophysiologic study. Using ice mapping, cooling at the region of the compact AV node resulted in block in the ascending fast pathway. When cooling subsequently was applied to the region of the slow pathway, tachycardia broke in the descending limb; thus AV nodal reentrant tachycardia was diagnosed on an anatomic and functional basis.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
