The digestive system is one of the essential systems in human physiology where the stomach has a significant part to play with its accessories like the esophagus, duodenum, small intestines, and large intestinal tract. Many individuals across the globe suffer from gastric dysrhythmia in combination with dyspepsia (improper digestion), unexplained nausea (feeling), vomiting, abdominal discomfort, ulcer of the stomach, and gastroesophageal reflux illnesses. Some of the techniques used to identify anomalies include clinical analysis, endoscopy, electrogastrogram, and imaging. Electrogastrogram is the registration of electrical impulses that pass through the stomach muscles and regulate the contraction of the muscle. The electrode senses the electrical impulses from the stomach muscles, and the electrogastrogram is recorded. A computer analyzes the captured electrogastrogram (EGG) signals. The usual electric rhythm produces an enhanced current in the typical stomach muscle after a meal. Postmeal electrical rhythm is abnormal in those with stomach muscles or nerve anomalies. This study considers EGG of ordinary individuals, bradycardia, dyspepsia, nausea, tachycardia, ulcer, and vomiting for analysis. Data are collected in collaboration with the doctor for preprandial and postprandial conditions for people with diseases and everyday individuals. In CWT with a genetic algorithm, db4 is utilized to obtain an EGG signal wave pattern in a 3D plot using MATLAB. The figure shows that the existence of the peak reflects the EGG signal cycle. The number of present peaks categorizes EGG. Adaptive Resonance Classifier Network (ARCN) is utilized to identify EGG signals as normal or abnormal subjects, depending on the parameter of alertness (). This study may be used as a medical tool to diagnose digestive system problems before proposing invasive treatments. Accuracy of the proposed work comes up with 95.45%, and sensitivity and specificity range is added as 92.45% and 87.12%.
消化系统是人体生理学中必不可少的系统之一,胃在其中起着重要的作用,其附属器官包括食管、十二指肠、小肠和大肠。全球许多人患有胃节律紊乱,同时伴有消化不良(消化功能异常)、不明原因的恶心(感觉)、呕吐、腹部不适、胃溃疡和胃食管反流病。用于识别异常的一些技术包括临床分析、内窥镜检查、胃电图和成像。胃电图是记录通过胃肌肉传递的电脉冲并调节肌肉收缩的一种方法。电极感测来自胃肌肉的电脉冲,并记录胃电图。计算机分析捕获的胃电图(EGG)信号。正常的电节律在餐后会在典型的胃肌肉中产生增强的电流。餐后电节律异常表明胃肌肉或神经异常。本研究考虑了普通个体、心动过缓、消化不良、恶心、心动过速、溃疡和呕吐的 EGG 进行分析。数据是与医生合作收集的,用于分析患有疾病和日常个体的餐前和餐后条件。在使用遗传算法的 CWT 中,使用 db4 在 MATLAB 中以 3D 图的形式获取 EGG 信号波模式。该图显示,峰值的存在反映了 EGG 信号周期。存在的峰值数量对 EGG 进行分类。自适应共振分类器网络(ARCN)用于根据警觉参数()识别 EGG 信号是正常还是异常。本研究可以作为一种诊断消化系统问题的医学工具,在提出侵入性治疗之前使用。所提出工作的准确性达到 95.45%,并且添加了灵敏度和特异性范围,分别为 92.45%和 87.12%。
