Acquisition and analysis of electrogastrogram for digestive system disorders using a novel approach

The digestive system is the one of the important system in the human body, which plays major role directly or indirectly for the function of human body. Most of the people around the world have the digestive system disorders due to improper digestion of food due to inefficient performance of stomach activity. The main objective of this paper is to propose a novel method of finding the digestive system disorders using electrogastrogram [EGG], which is a non-invasive, cheap and painless method by detecting the electrical signal from the stomach cutaneously and also it act as a preliminary investigation without a need for endoscopy which is painful investigation. The recording setup explained in this proposed system includes LabVIEW software and hardware which is used to record the EGG for more than hundred patients, nearly 75% of the patients suffered from results in digestive system disorders such as Dyspepsia, Stomach ulcer, nausea, cyclic vomiting syndrome, etc. For the above said digestive system disorders dissimilarity is found in its frequency and amplitude compared with its normal individual parameter (3 cpm) at a fair amount of accuracy.

I. Introduction

An Electrogastrogram (EGG) is a non-invasive test used to measure gastric myoelectrical activity [2], [18]. The normal gastric myoelectrical activity consists of a slow wave and spike potential. The abnormality arises due to recurrent nausea, vomiting, Dyspepsia, Stomach ulcer, Cyclic vomiting syndrome, etc which signals that the stomach is not emptying food normally. If the electrogastrogram is abnormal, it confirms that the problem probably is with the stomach's muscles or the nerves that control the muscles. This paper deals with the novel approach of recording of the electrical signals that travel through the muscles of the stomach and control the muscle's contraction. The EGG can be considered as an experimental procedure since its exact role in the diagnosis of digestive disorders of the stomach has not been defined yet.
