Use fine-grained ECGdeli measurement primitives from a cached session. Prefer this skill when an agent needs to cut one wave, retrieve one fiducial point, measure one interval, or fetch one amplitude or height from a samples x leads ECG matrix.
Run ECGdeli MATLAB-based ECG delineation and feature extraction from Codex. Use when an agent needs to annotate ECG wave fiducial points, extract ECGdeli amplitude or interval features, validate ECGdeli on local MATLAB, or call the bundled Python wrapper around MATLAB for ECG signal matrices or CSV files.
