Abstract

Our study was conducted among 44 healthy individuals who volunteered to perform electrogastrography - EGG to describe the gastric dominant frequency (DF) and stimulus factors. Electrodes were placed on the abdominal skin which refers to the gastric position; EGG were recorded at 2 time points, pre and post-test meal. The mean DF was 2.98 ± 0.37 circle/min. Percentage of normal slow wave frequency increased while dominant frequency instability coefficient (DFIC) decreased after test meal, but there was no statistical significance (p > 0.05). Most of EGG metrics were not significantly different between distinct age and sex groups, an exception for power ratio (PR) which was significantly higher in those older than 40 years old (p = 0.01). Our results in EGG parameters could suggest the reference values in normal Vietnamese people.
