CLINICAL-SIGNIFICANCE OF GASTRIC MYOELECTRICAL DYSRHYTHMIAS

Normal rhythmic myoelectrical activity of the human stomach is 3 cpm, regulating gastric contractile activity. Dysrhythmia in gastric myoele ctrical activity is found to be associated with functional disorders o f the stomach. Gastric dysrhythmias are classified into tachygastria ( frequency higher than normal), bradygastria (frequency lower than norm al) and arrhythmia (no rhythmic activity). Clinical significance of ga stric dysrhythmias is discussed in this paper, outlined as follows: (a ) What is normal gastric myoelectrical activity and what is dysrhythmi a? (b) How to detect gastric dysrhythmias? (c) Gastric dysrhythmias in clinical settings. (d) What may cause gastric dysrhythmias? (e) How t o normalize gastric dysrhythmias?
