“…EGG dominant frequency: the frequency at which the power was highest within the range of 0.02-0.107 Hz (1.2-6.4 cpm) of an entire EGG recording. It has been suggested that the dominant frequency of the EGG reflects the frequency of the gastric slow waves (Familoni et al, 1991;. 2.…”

AbstractsTo investigate the effect of oral glucose intake on gastric motility, we measured gastric myoelectrical activity and gastric emptying on two test conditions: 1) glucose intake and 2) water intake in the same 10 healthy male volunteers (20 to 29 years old). Gastric motility was evaluated with cutaneous-recorded electrogastrography (EGG) for 30 min both on fasting and after glucose or water intake, while gastric emptying was measured using acetaminophen-absorption method. There were no significant changes in EGG dominant frequency after water intake, but the frequency increased significantly after glucose intake. A postprandial dip (i.e., a transient decrease in frequency immediately after the food intake) was observed in 3 subjects after water intake and in 8 subjects following glucose intake. The EGG power ratio was significantly larger after glucose than water intake, with delayed gastric emptying in the former case. These results suggest that glucose is one of the components responsible for postprandial gastric motility.

“…Electrogastrography allows for the cutaneous measurement of GMA (Familoni, Bowes, Kingma, & Cote, 1991;Mintchev, 2000;Palmieri, Schulze-Delrieu, & Raab, 1992;Parkman et al, 1997;Pfaffenbach et al, 1998;Rezende-Filho, 1995). Researchers using EGG have demonstrated the ability to distinguish patterns of GMA in healthy subjects from patterns observed in the presence of disease (Geldof et al, 1986;Pfaffenbach et al, 1995).…”

“…Electrogastrography measures reflect the slow wave or baseline activity as well as changes in contractility that occurs within a period (Mintchev, 2000;Pfaffenbach, Adamek, Kuhn, & Wegener, 1995;Smout, Van Der Shee, & Grashus, 1980). The normal EGG frequency has been reported between 2 to 4 cycles per minute (cpm), with a normal post-prandial increase in amplitude of 1mV (Bellahsene, Schimer, Updike, & McCallum, 1992;Familoni, Bowes, Kingma, & Cote, 1991;Mintchev, 2000;Pfaffenbach, Adamek, Kuhn, & Wegener, 1995).…”

“…This cyclic motor activity occurs in a propagating fashion, propelling materials through the digestive system (Camilleri & Prather, 1998;Davenport, 1982;Koch & Stern, 1996;. Gastric myoelectrical activity can be measured non-invasively, using EGG, in either a laboratory setting or as an ambulatory exam (Bellahsene et al, 1987;Familoni, Bowes, Kingma, & Cote, 1991;Geldof et al, 1986;Koch, 1999;Mintchev, 2000). The cutaneous measurement of myoelectrical activity is accomplished by placing electrodes over the axis of the stomach, which allows for capturing electrical activity of the upper GI tract.…”

“…The electrical activity of the stomach, much like that of the heart, follows a rhythmic, oscillating pattern. The tracings obtained record the pattern of GMA in both the fasting and post-prandial states, providing information about the gastric electrical control activity baseline frequency (slow waves), electrical response activity (spikes) and rhythm (bradygastria, tachygastria, or dysrhythmias) (Bellahsene et al, 1987;Familoni et al, 1991;Koch, 2001;Maughan & Leiper, 1996;Mintchev, 2000;Smout et al, 1980). Cycles have been determined to range between 2 and 4 cycles per minute (cpm), with the established norm from 2.7 to 3.2 cpm (Bellahsene et al, 1987;Familoni, 1994;Familoni et al, 1991;Koch, 2001;Mintchev, 2000;Pfaffenbach et al, 1995;Rezende-Filho, 1995).…”

This descriptive, correlational study investigated the associations among gastric myoelectrical activity (GMA), upper gastrointestinal (GI) symptoms, and glucose control.The study also attempted to determine whether any relationship existed between upper GI symptoms, glucose control, age, or length of diagnosis and pattern of GMA identified using electrogastrography (EGG).A total of 25 persons participated in the study. The sample was comprised of 7 healthy controls, 5 patients diagnosed with type 1 diabetes, and 13 patients diagnosed with type 2 diabetes. Demographic data, a health history, blood sampling, and assessment of historical and current upper GI symptoms were obtained. Electrogastrography was performed for 30 minutes in the fasting state and continued at 30-minute intervals for a total of 1-1/2 hours post-prandially. Data from the fasting, 30-minute post-prandial period, and 120-minute post-prandial periods were analyzed for the study.For research question one, non-significant p values were confirmed during fasting (p = .14) and 120-minutes post-prandial (p = .11). A significant p value was noted at 30-minutes post-prandial (p = .04). This suggests that no difference exist between patterns of GMA in healthy subjects and patients with diabetes except during the period immediately after eating. No significant differences in the pattern of GMA were identified in type 1 versus type 2 diabetic patients during any sampling period (p = .81, .49, and .88, respectively).Research question 2 looked at GMA during 3 periods. At the end of the fasting period (period 1), there were 7 patients with normogastria, 10 with bradygastria, and 1 vi with tachygastria. The bradygastric group reported greater mean scores for symptom presence and severity historically and during the fasting period on all upper GI signs and symptoms. During period 1, mean scores for satiety on the TSS scale were the only variable yielding any significant result (p = .04). For this sample, no relationship was found between the three patterns of GMA and acute blood glucose, metabolic control, age, or length of diagnosis in patients with diabetes who were fasting. During the first post-prandial period (30 minutes post meal; period 2), 4 subjects were normogastric, 7were bradygastric, and 7 were tachygastric. There were no significant differences found between the distributions of scores for the variables under study and patterns of GMA.During the 120-minute post prandial period (period 5), 6 subjects were normogastric, 7were bradygastric, and 5 were tachygastric. There were no significant differences found between the distributions of mean scores for the variables under study and patterns of GMA.In conclusion, findings of this study support the potential use of EGG as a screening tool in the detection of patterns of GMA in healthy and diabetic individuals.Using EGG, gastric myoelectrical activity can be identified in both healthy controls and patients diagnosed with diabetes. Further studies are needed to generate data that can be used to ...
