Projet name

ECG_analysis

Description

This repository provides an open source Python toolbox from ECG analysis:

  • ECG signal denoising
  • QRS extraction
  • HRV analysis
  • Time frequency representation
  • Classification

It relies on a melting pot of already existing Python libraries that are referenced.

The results can be displayed through Jupyter Notebook

Usage

Use a single-channel ECG (electrocardiogram) as input and specify the ECG acquisition frequency.

QRS extraction

We proposed different standard algorithms for QRS extraction and R-R interval computation:
Algorithm name , Github documentation, Research article reference

  • XQRS algorithm, MIT-LCP/wfdb-python [Github], variation of GQRS

  • Construe algorithm, citiususc/construe [Github], On the adoption of abductive reasoning for time series interpretation, T. Teijeiro and al. (2018) [ref]

HRV analysis

We proposed to compute differents standard HRV indicators:

  • Time domain features: Mean_NNI, SDNN, SDSD, NN50, pNN50, NN20, pNN20, RMSSD, Median_NN, Range_NN, CVSD, CV_NNI, Mean_HR, Max_HR, Min_HR, STD_HR
  • Geometrical domain features: Triangular_index, TINN
  • Frequency domain features: LF, HF, VLF, LH/HF ratio, LFnu, HFnu, Total_Power
  • Non Linear domain features: CSI, CVI, Modified_CSI, SD1, SD2, SD1/SD2 ratio, SampEn

using the Aura-healthcare/hrvanalysis library [Github]
