Full Line of Solutions for Electrogastrogram Recording & Analysis

Wired, wireless, and MR EGG solutions available

Measure the time-varying gastrointestinal electrical activity of human and animal subjects, using invasive or noninvasive techniques

AcqKnowledge EGG Data

EGG Recording & Analysis for Human and Animal Studies

Measure the time-varying gastrointestinal electrical activity of human and animal subjects, using invasive or noninvasive techniques. AcqKnowledge® includes all the necessary tools for accurate Electrogastrogram recording and analysis. For additional flexibility, record data wirelessly with the BioNomadix® BN-EGG module, or the Mobita 32-channel system. Analyze data using the EGG presets and examine the gastric wave classifications in detail using the automated Gastric Wave Analysis tools.

EGG App Gastric coupling

These powerful, yet simple-to-use features automatically calculate and display the percentage of gastric CPM (contractions-per-minute) that fall within frequency band ranges corresponding to normal, bradygastric, or tachygastric waves. The applied EGG analysis also displays any percentages falling outside of the defined boundaries as a separate “arrhythmia” category.

EGG Gastric Coupling EGG Signal in AcqKnowledge

Factory preset ranges for commonly-used subject and wave types include Human – Gastric Slow Wave, Dog – Gastric Slow Wave, and Dog – Small Intestinal Slow Wave. A Custom preset option allows easy setup and saving of user-defined parameters for normal, bradygastric or tachygastric frequency ranges, and all analysis results can be seamlessly exported to the AcqKnowledge® Journal via the “Output to Journal” checkbox option.

Use auto-regressive frequency analysis to determine gastric wave classifications present in single or coupled EGG signals.

Available BIOPAC® EGG solutions include:

  • BioNomadix®: Wireless Dual-Channel EGG AMplifiers with the MP150 System
  • EGG100C: Tethered amplifiers with spot electrodes, or electrode caps and the MP150 system
  • Mobita®: 32 Channels of wireless biopotential data, live or logged
