ECG-based functions - Githubissues

shah-in-boots commented 5 months ago

Ideas for ECG-based analysis functions will go here. When reading in 12-lead ECGs, should be able to very easily parse them into useful parameters.

[ ] Wilson's vector gradient, and the subcomponents described as global electrical heterogeneity
[ ] High frequency HRV based on the fast Fourier transform
[ ] P wave indices (particularly P wave axis and its variability)

@dsean2112 Thoughts?

I have functions ready for:

HF HRV using RMSSD (seems to be the best analysis for 10 sec ECGs)
General wave-axis calculator. Input is 12 lead signal and 12 lead ECG. Output is a 3D vector using the kers matrix. Function uses AUC relative to the isoelectric point. Can be used to find fluctuations
P-wave amplitude
GEH and supporting functions for input. Translated Dr. Tereshchenko's code from MATLAB

The HRV and p-wave amplitude are simple, pretty confident in those. Wave-axis and GEH are more involved and have more room for error...
