[Selective electroenterogastrography. I]

A new model of electroenterogastrograph has been designed. Besides of amplification it can divide the total bioelectrical activity into several flows, and distinguish potentials specific to the certain organ or its part. Each flow is depicted on a separate channel of the electroenterogastrograph. It makes it possible to increase the diagnostical value of the method. It is necessary to learn specific parameters of potentials of the organs to be tested. To register electrogastrogram it is necessary to use frequencies of 0.04-0.07 Hz; electroduodenograms 0.18-0.22 Hz, etc.
