RESUMO

The electrocardiogram (ECG) is a tool used for diagnosis of diseases related to the heart. This work has the purpose of detecting QRS complex, focusing on the R wave, which represents the ventricles’contraction. It is presented two techniques of processing ECG signals. The first uses Pan &Tompkins algorithm based on digital filtering. The second uses the discrete wavelet transform, which represents the characteristics of the signal simultaneously in time and frequency. It is presented a comparison of the efficacy of both algorithms, which are implemented in FPGA, using serial processing based on a C programmed microcontroller, and parallel processing entirely in VHDL, with the purpose of comparing the time of processing. The results suggest that future work can be based on the investigation of other wavelets family for detecting QRS complex in ECG signals and other methods of implementing filters in FPGA.
