Porcine Left Atrial Wall Stress After Ventricular Tachypacing Mimicking the Effects of Early Atrial Fibrillation
Bibliographic record
Abstract
Atrial Fibrillation (AF) is the cardiac arrhythmia most commonly encountered in clinical practice. Current statistics referring to the US population indicate a prevalence of AF up to 2.2 million people, projected to increase to 2.66 million by the end of 2010. AF has a high impact on society in terms of human costs, with an annual mortality rate of 11,438 patients. AF also increases the risk of ischemic stroke at least by a factor of 4 and it is responsible for at least 15% of all ischemic strokes, which represent the main cause of long-term disability and one of the main contributors to health care costs [1]. AF results from the synergic action of electrophysiological, biochemical and structural remodeling. Ventricular tachypacing (VTP) has been successfully used in animal models to reproduce relevant features observed in patients suffering from AF, such as ion-channel alterations, fibrosis development and atrial dilatation [2] [3].

How this classification was reachedexpand
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.
