title: [Cutaneous electrogastrography: a new incorporated technique for the study of gastric motility].
abstract: BACKGROUND
  Gastric electrical activity can be accurately recorded and analyzed by cutaneous electrogastrography. Different types of abnormalities have been described in a variety of disorders.
  
  
  OBJECTIVE
  To analyze a group of asymptomatic subjects and assess the prevalence and patterns of dysrrhythmias in patients with type 1 and 2 diabetes and patients with functional dyspepsia.
  
  
  METHODS
  One hundred subjects were studied (32 male, mean age 45 years old, 10 asymptomatic, 11 type 1 diabetics, 22 type 2 diabetics and 57 subjects with functional gastrointestinal disturbances). Gastric myoelectrical activity was recorded using surface electrogastrography for 1 hour in the fasting state and 1 hour after a test meal (350 kcal).
  
  
  RESULTS
  The electrogastrogram was normal in 90% of asymptomatic controls. It was abnormal in 64% of type 1 diabetic patients, in 55.5% of type 2 diabetic patients and in 61% of patients with functional dyspepsia. Different types of dysrrhythmias were observed in each group.
  
  
  CONCLUSIONS
  Electrogastrography might define a subgroup of patients with electrical rhythm disturbances, that may have a different approach to treatment than patients with normal gastric electrical activity.
