Authors

GEH calculation code V.1 Erick Andres Perez Alday, PhD, perezald@ohsu.edu Annabel Li-Pershing, BS, lipershi@ohsu.edu Muammar Kabir, PhD, muammar.kabir@gmail.com Larisa Tereshchenko, MD, PhD, tereshch@ohsu.edu Last update: February 20th, 2018

GEH Calculation

See pdf file in the repository for GEH parameter calculation methods.

GEH MATLAB Code

See GEH_analysis_git.m file in the repository for GEH parameter calculation. Test file is provided (90757.mat) for algorithm testing. Kors_git.m file is a code for Kors transformation (transforms 12-lead ECG to XYZ (Frank) ECG)

Test files

One test file (90757.mat) is provided for GEH calculation testing. Sampling rate 500 Hz. Amplitude resolution 1 µV. Raw 12-lead ECG file (12LECG.mat) is provided to illustrate Kors transformation from 12-lead to XYZ (Frank) ECG
