Bipolar ablation with half normal saline for deep intramural outflow tract premature ventricular contraction
Bibliographic record
Abstract
Key Teaching Points•In ventricular arrhythmias, an intramural septal origin should be suspected in case of poor precocity or pace map in either side of the septum, far-field local electrograms, and/or diffuse areas of earlier activation recorded on the mapped surfaces.•Bipolar ablation using half normal saline as irrigant can be effectively and safely performed to treat intramural septal ventricular arrhythmias when conventional ablation has failed.•Gradual titration of power, real-time monitoring with intracardiac echocardiography, and close attention to impedance and temperature are recommended to minimize complications. •In ventricular arrhythmias, an intramural septal origin should be suspected in case of poor precocity or pace map in either side of the septum, far-field local electrograms, and/or diffuse areas of earlier activation recorded on the mapped surfaces.•Bipolar ablation using half normal saline as irrigant can be effectively and safely performed to treat intramural septal ventricular arrhythmias when conventional ablation has failed.•Gradual titration of power, real-time monitoring with intracardiac echocardiography, and close attention to impedance and temperature are recommended to minimize complications.

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.
