Computer-assisted ambulatory long-term manometry of tubular esophagus

A two-channel 24-hr digital recording of esophageal pressure generates about 20 times more data than an esophageal pH-metry if an appropriate high sampling rate is used and unreduced data are stored. Because of this large amount of data, manual data evaluation is no longer feasible, and a computer-assisted procedure becomes necessary. The system presented here consists of a combined one-channel pH and two-channel pressure probe, a digital data …
