Description

The package `QRSdetection.m` contains all the functions necessary for non-real time implementation of the QRS complex detection algorithm for an EKG signal sampled with 200Hz sampling frequency. This includes the following: lowpass (cutoff frequency ~11Hz) and highpass (cutoff frequency ~5Hz) digital IIR integer filters; digital differentiator; squaring function; digital moving window integrator (the window width is 30 samples, which corresponds to 150 msec); the complete detection function.

A demonstration notebook `QRSdetectiondemo.nb` is provided, where all functions of the package were applied to a sample EKG.

The data file `EKGdata_01.txt` with the sample EKG is provided.
