“…We recorded EGG during the fasting period , because the standard test meal may not be equally loaded to elderly subjects as to the young subjects which may mislead the findings . In our previous observations in diabetic patients (Okuno et al ., 1990), abnormal EGG waves were recorded both in fasting and post-prandial period . This may indicate that EGG recording in fasting period is essentially equivalent to postprandial EGG in terms of rhythmicity .…”

“…Smoking was prohibited on the recording day until the end of the study. Surface EGG was recorded as described elsewhere (Okuno at al., 1989;Okuno et al, 1990). Recording was performed in a supine position, using Ag-AgCl electrodes (Lectrode, NEC-San-Ei, Tokyo, Japan) placed on epigastric skin surface after abrasion of the skin by rubbing it with the pretreatment gel (Hi-Clean, Fukuda M.E.…”

“…With this surface EGG, various electrical abnormalities were found in several clinical condi tions (Geldof, et al, 1986;Abell et al, 1987;Stern et al, 1987;Abell et al, 1991;Koch et al, 1989;Okuno et al, 1990;Chen et al, 1992;Riezzo et al, 1992).…”

To investigate the alteration of the gastric electrical activities by aging, we performed electrogastrography (EGG) on 13 asymptomatic young human subjects under 60 years old (the young group) and 12 subjects over 60 years (the elderly group). Surface EGG was recorded at fasting state for 30 minutes in each subject. We expressed the frequency distribution of surface EGG in each subject with the median value of frequency distribution (FMED) to represent the center of the electrical activities, and the interquartile range of frequency distribution (FIQR) as the indicator of regularity . FMED in the young group was 3.0:(median:[range]) cycles per minute (cpm), while it was 3.3:[3.0, 4.0] in the elderly group which showed statistically a significant difference between the groups (p= 0.01). FIQR in the young group was 0.5:[0.1, 1.8] and that in the elderly group was 0.55: which was not significantly different statistically. These data showed that aging increases the frequencies of the rhythm of surface EGG, without disturbing its regularity.This change may be a part of a spectrum of physiological changes accompanied with aging, and are unlikely to have clinico-pathological significance.
