The Gastric Alimetry® system measures the electrical slow waves generated by the stomach’s pacemaker cells, the upstream signals that initiate and coordinate every contraction. During a supervised four-and-a-half-hour test in a clinic or hospital, a high-resolution sensor array of 64 electrodes is applied to the patient’s abdomen to record gastric electrical activity continuously. Advanced signal processing and AI-assisted analysis then interpret the complex electrical patterns generated, producing validated, clinically actionable outputs. Patients also log their symptoms in real time through a validated companion app, allowing direct correlation between electrical findings and the patient’s specific symptom experience.
