Database of 3D ECG and Metrics for Ischemic State Analysis

This database contains Python scripts for processing three-dimensional (3D) electrocardiogram (ECG) data, generating distance matrices (XY and XZ projections), performing statistical analyses, and computing metrics such as perimeter, curvature, and almost-curvature. The scripts support clustering, hypothesis testing, and graphical visualization. These tools are part of an innovative research initiative focused on defining and developing a 3D ECG through the assignment of polar coordinates to ECG variables, as well as the formulation of a novel parameter (almost-curvature) with potential clinical significance for detecting evolutionary changes in 3D ECG deflections during acute myocardial ischemia.
