Effect of Differences in the Meal Ingestion Amount on the Electrogastrogram Using Non-linear Analysis

摘要

This paper reports a study of the impact of differences in meal ingestion amount on electrogastrograms. The study was performed by recording an electrogastrogram and an electrocardiogram of eight young men for 60 min once before and once after each test subject ingested meals with ingestion amounts of 800 kcal and 400 kcal. The results showed that meal ingestion affected the power spectral density of the tachygastria range (3.7-5.0 cpm) by significantly increasing its value after the meal. The differences in meal ingestion amount are expressed in the power spectral density of the colon range (6.0-8.0 cpm) by significantly increasing its value after the meal, but only when the subject ingested an 800-kcal meal.
