Abstract: Objective: To investigate the effect of gastric pacing on gastric electrical activity in patients with gastric dysrhythmias.Methods: Thirteen patients with gastric dysrhythmias were examined with electrogastrography (EGG),and their symptoms were assessed before and after gastric pacing treatment.Results: The patients'symptoms were significantly improved after gastric pacing treatment.The total response rate was 90.05%.The percentage of preprandial normal slow wave before and after treatment was (41.9±16.9)% and (46.9±21.6)%(P>0.05) respectively,with no statistical difference.The percentage of postprandial normal slow wave before and after treatment was (57.5±28.6)% and (78.7±16.6)%(P<0.05) respectively,with significantly statistical difference.Conclusions: Gastric pacing could improve gastric electrodysrhythemia and ameliorate symptoms in shorttime for patients with gastric motility disorders.
