Developmentn of A Three-Lead Electrocardiograph with Embedded Digital Filter on FPGA for Noise Removel
Abstract: An ECG is a
bioelectrical signal which has important correlation with electrical activity
of the heart. The ECG reflects important information regarding the performance
of the heart. ECG devices are currently made for different settings
applications including patient’s home, ambulance, general practioner offices,
emergency wards or public health center. Most of the commercial ECG machine
available today is still expensive for public health service in the rural area.
Therefore, there is a need to develop a low cost and high performance of
three-lead ECG machine which can be used for the medical doctor or health
practitioner in the rural area. In general, the ECG machine consits of
differential amplifier, filters, isolation amplifier,buffer, analog to digital
converter, microcontroller with digital signal processor and displaying unit.
However, the biggest problem in designing the ECG machine is on the problem
with low signal-to-noise ratio. Since, there are many sources of noise such power
line interference, DC drift, EMC contraction, electronic noise, and motion
artifacts. The goal of the work is to design and develop a low cost ECG machine
with digital signal processor for noise removal. For that purpose, a series of
digital filters will be embedded in the Xillinx Spartan 6 FPGA as part of
digital signal processor. Results show that the prototype of ECG machine can be
successfully recording and displaying the ECG signals with the good
performance.
