title: A computerized data analysis method for electrogastrographic signals.
abstract: Many recent studies showed that EGG signal can be used to diagnose and monitor patients with gastric motility disorders.
  
  
  METHODS
  This paper presents the way to record and process the EGG signal, and the results of study on a sample of 10 patients. These patients are initially evaluated by upper endoscopy were are normal without gastric motility dysfunction or some gastric lesions. The EGG signals are obtained with the surface electrodes placed along the projection of the stomach axis on the abdomen, amplified with an electrogastrogram amplifier module and analyzed on a personal computer. The used signal analysis method is based on spectral analysis of EGG signals.
  
  
  RESULTS
  This method showed a normal gastric activity for seven patients of the sample and a gastric dysryhthmia for three of them.
  
  
  CONCLUSIONS
  The computerized spectral analysis of electrogastrography signals proves to be a non-invasive, high sensitive, reproducible and cost-effective method for the diagnosis of gastric dysrhythmias and normal gastric electrical rhythm even in sub clinical patients.
