On the electrocardiographic findings in the gastrointestinal diseases, especially on the changes in the RS-T segment and T wave.

The changes in the RS-T segment and T wave are not infrequently observed in electrocardiograms of various gastrointestinal diseases. The nature and the clinical significance of these findings were discussed in this report. The RS-T and T changes observed in gastrointestinal cancer, liver cirrhosis and hepatitis are considered to be ascribed to the hypalbuminemia and/or the hypopotassemia. In the biliary tract diseases, the RS-T and T changes can be attributed to the coronary disorders, which may be functional, organic or both. The changes observed in peptic ulcer and gastroptosis may be interpreted to be due to the autonomic nervous dysregulation or circulatory dysfunction.
