摘要：

The aim of the article is to present the problem of processing and analysis of electrical activity of the gastric system, known as Elecrogastrography (EGG). The signals can be acquired in an invasive or noninvasive way with cutaneous electrodes. In the invasive recordings one can see components in form of electrical control activity (ECA), that are hardly to recognize in cutaneous EGG. Thanks to adequate tools, as wavelet transform, it is possible to reconstruct ECA from EGG recordings in the way that processed EGG are similar to those observed in invasive recordings. The described results of the work are preliminary, but they tend to be promising. (Extraction of characteristic features of electrogastrographic signal using wavelet transform)
