Abstract

To investigate the correlations between electrogastrogram (EGG) and gastric emptying (GE) in children with functional dyspepsia (FD). A total of 51 children with FD and 25 healthy children as control were enrolled into this study. Polygraph ID 4-channel EGG analysis system was used for EGG recording and gastric emptying of solids was studied by using a standardized egg meal labeled with (99m)Technetium sulfur colloid for each subject. (1) Compared with the control group, the percentage of normal slow wave (N%) in the FD group was significantly lower than that of the control group (P < 0.01). Children with FD had higher rates of abnormal EGG, in which 32 cases showed mixed dysrhythmia preprandial and postprandial recordings (62.7%). (2) The two groups had significant difference in ratio of the percentage of preprandial dominant power (DP) to postprandial DP (P < 0.05), it showed that the postprandial DP of the FD group did not increase. (3) The postprandial dominant power instability coefficient (DPIC) as well as preprandial DPIC and dominant frequency instability coefficient (DFIC) in the FD group were increased. The coupling of the slow wave of preprandial and postprandial EGG in the FD group (26.95 +/- 13.69, 26.93 +/- 12.63 ...Continue Reading

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
