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