[Limitations and possibilities in the determination of transmural gastric potential in humans].
"Determination of the Transmural Gastric Potention, Limitations and Possibilities" presents a new approach for measuring the transmural gastric potential difference with computerized calculations of parameters. A "Reizindex" is introduced as a new secondary parameter describing the process of irritation better than Pdmax or area or area under the baseline. A second secondary parameter the "mean instability time of the membrane" is also introduced as a very stable parameter as far as the whole process is concerned. (first moment) The relevance of the model is proved by baseline data of 16 volunteers and investigations with a strong H2-blocker.
