The percentage of 3 cpm ; Four-channel EGG ; Running spectrum analysis(RSA) ; Relative electrode position
Electrogastrography(EGG) is a method of measuring gastric electrical activity on the abdomen. Although it is noninvasive and inexpensive. EGG signals have a very low frequency (0.2~10cpm) and extremely low amplitude(10~100㎶). Consequently, its measured waveforms are quite difficult to analyze and it is not completely understood yet. In this study, a four-channel EGG measurement system with Running Spectrum Analysis was built to measure and analyze the action potentials of the stomach. This System was compared with the commercially available one-channel Digitrapper EGG. The percentages of 3 cpm were compared with the best channel of the four-channel system and channel 1, whose electrode position was approximately the same as that of the commercially available one-channel system for normal subjects. The respectively, and it was statistically significant(p<0.001). The average 3 cpm percentages of the best channel and channel 1 for postprandial measurement were 90.4% and 76.5%, respectively, and it was also statistically significant(p<0.001). From these results. it was confirmed that a 4-channel EGG system is better than a 1-channel one for EGG measurement.
