ArrhythmiaPT

Description

This repo contains a complete app for processing and classifying (with support vector machine - SVM) ECG signals recorded with an external device. Currently only works on offline test signals.

The most interesting signal processing implementations can be found here:

https://github.com/EmilOJ/ArrhythmiaPT/blob/master/app/src/main/java/com/helge/arrhythmiapt/SignalProcessing.java

and includes:

• a complete QRS detection algorithm implementation (Pan-Tompkins)
• various utility functions known from MATLAB such as
  • svm_classify() given weights and biases
  • filtfilt()
  • circshift()
  • demean()
  • mean()
  • median()
  • diff()
  • etc...
