Abstract
The communication from right to left through the interventricular septum of the heart became identified by the anatomical study for 4 years. One thousand nine hundred years ago, Galen stated that blood seeps through the perforations in the interventricular septum of the heart. However, William Harvey, working 400 years ago, failed to find any. The interventricular vessel is a slit between the fibers of the muscle feasible to be patent by relaxing and widening of the helical heart at the right atrial filling phase at the end of the diastole. The case exhibited the flow of venous blood passing from right to left through the interventricular vessel at the right atrial filling phase concordant to the fourth heart sound. The earliest left ventricular activation closed the interventricular sphincter surrounding the interventricular vessel in the middle of the left muscular part of the interventricular septum. The fourth heart sound is common at the atrial filling phase in hypertrophy of systemic hypertension and in ischemic heart disease. It is necessary to explore vigorously the unknown etiology of the fourth heart sound (S4).

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.
