An FPGA System for QRS Complex Detection Based on Integer Wavelet Transform

This paper presents the QRS complex detection design suitable for implementation in Field Programmable Gate Array (FPGA). It employs the simplest version of Integer Wavelet Transform for signal decomposition and techniques of zero crossing and double tresholding for extraction of R peaks which makes it suitable for application in real-time and cost effective personal healthcare assistance devices. Beside theoretical elaborations, the system architecture, simulation diagrams and working performances are presented.
