Análise de Sinais de Eletrocardiograma utilizando FPGA

Abstract

The electrocardiogram sinais originate from the electrical activity of the heart. By means of electrodes, it is possible to capture these sinais for diagnosis of diseases, heart rate determination and other medical information. The electrocardiogram signal receives interference from muscle activity, interference electromagnetic interference from the electrical network and noise coming from the electrical system itself signal acquisition. To analyze two electrocardiogram signals, either MATLAB software and FPGA programmable hardware (in English, Field Programmable Gate Array). The FPGA is a very useful digital processor in sinai processing due to its architectural flexibility, parallel processing capacity and operating speed. The objective of the proposed course completion work is the implementation of a digital conditioning and processing system signal of an electrocardiogram in FPGA. The results confirm that the system digital purpose is capable of acquiring and processing the ECG signal, so that Noise and disturbance filtering is done in real time. Beisdes the heart rate estimation algorithm measuremes the heart rate with only one cycle of delay.
