Selective Lead Integration: Enhancing ECG Classification for Effective Cardiac Monitoring
Bibliographic record
Abstract
The advent of telehealth technology has ushered in advanced avenues for remote, non-invasive health monitoring, precipitating a surge in the development and application of remote health monitoring platforms. Such platforms are increasingly integrated with sophisticated algorithms to enable timely detection and diagnostic alerts. Prominently, electrocardiogram (ECG) monitoring systems have become pivotal in diagnosing a myriad of cardiac conditions. However, modern cardiac monitoring paradigms exhibit a deficiency in understanding the nexus between diseases and the corresponding leads. This oversight not only diminishes the diagnostic accuracy but also incurs superfluous consumption of computational resources and data bandwidth, thus challenging the efficacy and sustainability of the monitoring process. This research introduces an innovative model tailored for the concurrent multiclass classification of ECG signals by leveraging a minimal and highly correlated set of leads. A performance assessment delineates that the proposed model attains a Receiver Operating Characteristic (ROC) range of 92.8%-99.7% in all 23 categories using only six leads, sur-passing existing ECG classification strategies that employ 12-lead ECG signals. Furthermore, empirical results underscore that our proposed strategy, even with its reduced lead count, achieves superior accuracy for three cardiac conditions and maintains equivalent accuracy for an additional 17 conditions according to the testing data set.

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.
