ECG Compression Library for Long-Term Monitoring of Heart Function in Mobile HealthCare Systems

Background and Motivation: 

It is known that cardiovascular and ischemic heart diseases are the leading cause of death in the developed countries. Long-term continuous monitoring of heart function provides a way to discover the problem early and take timely measures to prevent sudden heart attack.

A variety of wearable devices are available in the market with the feature of electrocardiogram monitoring. These devices can be connected with smartphones and provide data for applications. According to forecasts of research2guidance experts the smartphone applications will become the killer applications in mHealth solutions in the near future.

Nevertheless, long-term continuous monitoring leads to a problem of huge amounts of electrocardiogram data. Recently a number of efficient compression algorithms have been developed for ECG signal processing. These algorithms need to be adapted for using in mobile applications.

Project Summary: 

Within the project we are developing the cross-platform ECG compression software solution on the base of available algorithms, taking into account mobile computing constraints. The solution is developed in the form of  easy-to-use library that provides lossy compression method based on discrete wavelet transform with following features:

  • High compression ratio;
  • Reconstruction possibility of important medical features of initial signal;
  • Phone battery tolerance.
Project goals and future research directions: 
<p>1. Development a cross-platform ECG compression library.<br /> 2. Integration to arrhythmia detection application in order to reduce traffic to clinical database.<br /> &nbsp;</p>
