Abstract

This paper proposes an on-line system for feature extraction from ECG signal. The QRS detector, RR interval calculator, heart rate calculator and additional modules are developed in VHDL code and embedded in a single FPGA chip. The overall design has a low hardware occupation, 1838 LEs, and minimal number of setting parameters, only two, sampling and clock rates. The achieved accuracy is 97.5%. As such, it is very suitable for embedding in wearable health care systems, portable instruments and telemedicine devices. The methodology for QRS detection, system architecture and preliminary testing results are presented.
