The ECG Recording
Bibliographic record
Abstract
The ECG waves are recorded in different forms according to the location of the explorer electrode. The morphology of the ECG is determined by the location at which the lead is recorded. ECG devices record the electrical activity of the heart through both frontal and horizontal plane leads. There are six frontal plane leads and six horizontal plane leads (V1–V6). This chapter explains some aspects of the ECG–VCG correlation using Burger's triangle. There is an increased interest in revising the standard presentation of the frontal plane ECG leads by changing the lead aVR location. Vectorcardiographic loops originate in the frontal or horizontal plane leads with different ECG morphologies, with QRS complexes more or less wide, and with positive, negative, or diphasic deflections in accordance with their projections in the respective positive and negative hemifield. The chapter focuses on the recording process and the technical errors that may occur during this process.

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.
