Insights
This study established normative electrogastrogram values in children, finding age and gender influence gastric myoelectrical activity. Interpretation requires considering these individual factors due to significant variability.
Area of Science:
- Pediatric Gastroenterology
- Electrophysiology
- Digestive Physiology
Background:
- Electrogastrography (EGG) is used to assess gastric myoelectrical activity.
- Normative EGG values in pediatric populations are not well-established.
- Understanding EGG variability is crucial for accurate clinical interpretation in children.
Purpose of the Study:
- To determine normative electrogastrogram values in healthy children.
- To investigate the influence of age and gender on EGG parameters.
- To establish reference ranges for pediatric gastric myoelectrical activity.
Main Methods:
- Surface electrogastrograms were recorded in 292 healthy children (ages 6-15).
- Recordings were performed in both interdigestive and postprandial states after a standardized yoghurt meal.
- Helicobacter pylori infection was excluded using a 13C-urea breath test.
Main Results:
- Significant between-subject variability in gastric myoelectrical activity parameters was observed.
- A statistically significant decrease in dominant frequency was noted with increasing age.
- Girls aged 12-15 years showed a lower postprandial rise in dominant power compared to other subgroups.
Conclusions:
- Age and gender are important factors to consider when interpreting pediatric electrogastrograms.
- The substantial between-subject variability necessitates caution during interpretation of pediatric EGG results.
- Establishing age- and gender-specific normative data is essential for reliable clinical application.
Unlabelled:
The study was designed to determine normative values of an electrogastrogram in healthy children.
Material And Methods:
Surface electrogastrograms were taken in the interdigestive state and after meal stimulation in 292 non-obese children in whom Helicobacter pylori infection was excluded with the use of a 13C-urea breath test. The cohort comprised the following subgroups: age 6-9 years--114 children (57 girls and 57 boys), age 10-11 years--88 children (44 girls and 44 boys), age 12-15 years--90 children (45 girls and 45 boys). Yoghurt was chosen as a test meal: 150 g (142 kcal) was given to children aged < or = 11 years, whereas children older than 11 years received 300 g (284 kcal).
Results:
Similarly to formerly published studies the parameters describing quantitatively the gastric myoelectrical activity exhibited considerable between-subject variability. A slight but statistically significant decrease in the dominant frequency was found with increasing age of the children. The subgroup of girls aged 12-15 years had statistically lower postprandial rise in the dominant power when compared to any of the other five subgroups.
Conclusions:
The results obtained imply a necessity of considering peculiarities related to age and gender when an electrogastrogram is performed in children. Taking into account the disclosed substantial between-subject variability of the electrogastrographic parameters in children caution is recommended while interpreting a result of an electrogastrographic examination.

An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...
