Acquisition, filtering and decomposition into real-time ECG signal with Ni—MyRio

Abstract:

In this project the signal acquisition caused by the electrical activity of the heart using the embedded device National Instruments Myrio performed. Because the heartbeat are impulses that manifest with very little current, it is impossible to process without first performing an amplification of the signal. The amplification in this project was divided into two segments, a pre-amplification integrated AD620 and post-amplification by AO TL084. To make the acquisition of data in real time the acquisition was realized in the FPGA device. Once acquired data to plot them on the processor FIFOs (Theory tailed) was used to prevent the loss of data due to the different operating frequencies in both the processor and the FPGA. Finally the signal processing is performed using wavelets to separate waves making up the ECG (P, QRS, T, U) for display separately.
