Abstract
Our aim was to study the electrical characteristics of human ventricular fibrillation (VF) by means of body surface potential mapping and heart-model simulations. We acquired 120-lead ECG data on the chest surface of patients undergoing controlled testing of implantable defibrillators. VF was induced by burst pacing, and ECGs were recorded for 5 to 7 seconds before the device delivered a rescue shock. We then used orthogonal decomposition to characterize spatial and temporal features of ECGs, and inverse solution to derive epicardial potential maps. To gain insight into mechanisms of VF, we used an anisotropic bidomain model of the human ventricular myocardium, featuring 5 ionic currents. The model showed meandering VF scroll waves exhibiting break-up and coalescence according to choice of ionic-current parameters. This combination of experiments and simulations offers a unique perspective on the origin of spatial patterns of ECG during VF.

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 it
