Design of a Microcomputer Based Realtime ECG Holter Device

Abstract

The growing aging population rate in our country and all over the world and increase in heart diseases lead to some requirements; in fact, it's indispensable to keep activities of this vital organ under control and observe all the effects of during and pre-treatment process. The primary goal of this study is to design a specifically developed device that will facilitate human life by any means of the specifications and implementation of portable ECG Holter device with open source software and upgradeable embedded system. The study that we have conducted consists of 3 phases; The 1st phase made it suitable to signal processing stage by compiling EKG signals with the aid of bioinstrumentation amplifier circuit that we developed. Afterwards, bioinstrumentation amplifier and signals raised by 205 times. In order to suppress network noise, 50HZ notch filter was implemented on ECG Signals and a Butterworth filter with the bandwidth of 0.01-130 Hz was used. In the 2nd phase, analog ECG sign, provided by the participants was digitized by using analog digital converters. It was linked up with embedded system cards via communication protocols. Three different types of embedded system cards and signal processing algorithm were setup and the interface that we designed was developed in Python language owing to a great number of libraries. However, it was replaced by another programming in C++ language since this language did not allow signal processing algorithm function well due to lack of operating speed. In the 3rd phase, ECG data was recorded after 10 different participants moved upstairs and downstairs at intervals of 100 sec, followed by breaks of 3 times.  Later on, the Raspberry Pi, Beaglebone and Odroid embedded system cards were compared in terms of speed differences and performances, and also consequences were analyzed. Since the sampling rate with Beaglebone didn't exceed 35 Hz, it was determined that this was inappropriate for the use of ECG. The sampling rate with Raspberry Pi remained around 80 Hz and it was confirmed that this could be used only for checking the pulse. As far as Odroid is concerned, since sampling rate went up to around 250 Hz, It was assigned to be the best microcomputer.
