A Real-Time Wavelet-Based Electrocardiogram Delineation System

The purpose of this project is to develop and optimize DWT-based ECG delineation techniques for real-time operation on the ShimmerTM wearable embedded platform. Different implementations are proposed, all of them based on the well known wavelet-based delineation technique, starting from single-lead delineation and moving towards multi-lead implementations that improve the accuracy, stability and resilience to artifacts of the delineation results. Moreover, we carefully optimize these algorithms for efficient execution on the ShimmerTM platform and explore energy and performance trade-offs to achieve two main challenges: 1) maintain good delineation results while performing the delineation in real time; and 2) reduce as much a possible the energy consumption by means of reducing the wireless communication and the execution time.
The delineation results and (optionally) the ECG signal, are transmitted in real-time to an iPhone, for high quality graphical representation.
