Study of Stomach Abnormalities Using ECG Signals

In this study various stomach abnormalaities and its corresponding gastric signals are analysed using MATLAB. Electrogastrogram is used to measure the electrical activity of the stomach. If there is any abnormalities in gastric digestion process, it will be reflected in EGG signal. In this study 40 EGG signals are acquired from healthy adults in the age group of 20–25 and the signals are acquired from center for biomedical research, VISTAS. All the individuals who were used for this signal acquired from the individual were given junk foods. The signals were taken in two conditions (i) at fasting state (ii) at postprandial state. The research mainly focus on digestion process and effects of packed foods during digestion process. BIOPAC MP45 device is used for signal acquisition and MATLAB version 2024 is used for analysis. The research work exhibits delayed in digestion in few individuals who regularly intakes junk food and the frequency estimation of EGG signal clearly shows the delay digestion with prolonged frequency range.
