AcqKnowledge v3.9 includes a fully automated Gastric Wave Analysis routine. Gastric Wave Analysis uses autoregressive time-frequency analysis to determine the classifications of gastric waves present in an EGG signal. The single wave analysis determines the percentage of gastric waves that fall within the frequency bands corresponding to normal, bradygastric, and tachygastric waves. The analysis also indicates the percentage of waves that fall outside of these boundaries and are arrhythmias. The frequency bands are expressed in units of ‚contractions per minute‚ and may be adjusted by the user. Presets for commonly used subject and wave types are predefined; you may extend these presets with your own.

This is one of many ADVANCED FEATURES for the selected Application. Scroll down for hardware options.
The routine also includes Gastric Wave Coupling takes two EGG signals and uses autoregressive techniques to classify the contractions in those signals according to user-configurable frequency bands (similar to single channel Gastric Wave Analysis). In addition to providing classification information for the two signals, Gastric Wave Coupling provides a measure of the percentage of coupling between the two signals—this measure that can be used to determine the amount of slow-wave propagation across the stomach.

Learn a technique—Trans-radial Electrical Bioimpedance Velocimetry (TREV)—that is more user-friendly and less invasive than the transthoracic method. TREV measures blood movement in the radial and ulnar arteries of the forearm via bioimpedance.
Topics Covered:
– Presentation and discussion of TREV
– Derived Indices Relevant to TREV
– Hardware setup
– Participant setup
– Recognizing good quality and bad quality data
– Demonstration with the grip anticipation test
– Review of results from other tests
