Dataset and Python Pipeline for 3D ECG Analysis: Perimeter, Curvature, Almost-Curvature, and Torsion

This dataset contains Python code, explanatory documentation, and output files for the analysis of three-dimensional electrocardiogram (3D ECG) trajectories in patients with LAD ischemia before and after coronary revascularization. It includes computed metrics (perimeter, curvature, almost-curvature, and torsion), statistical analyses, and illustrative figures, providing a reproducible framework for studying ischemia-related electrical remodeling.
