The real-time R-wave detection based on FPGA

R-wave detection is one of the most significant parts in Electrocardiogram (ECG) signal studies and plays an important role in the automatic ECG analysis system. In this research, we design a prototype of portable automatic ECG analysis system based on field programmable gate array (FPGA) using Altera DE2-70 development board. The system includes four parts: 1)Data input, 2)ECG denoising, 3)ECG analysis and R-wave detection, 4) Results display. In this paper, we use the data from the well-known MIT/BIH arrhythmia database. CDF9/7 wavelet filter is used to remove the high-frequency noise and the threshold method is used to detect the R-wave. In addition, In the Quartus II 9.0 development environment, we complete the simulation and synthesis. Experimental results based on the system show that proposed architecture can detect R-wave accurately and the utilization percent of resource is low, just 6%.
