Abstract

A method of telemetric measurement of antroduodenal myoelectrical activity (EMG) in freely moving pigs has been developed. Silver bipolar electrodes were sutured on the antrum and duodenum and connected to a telemetry transmitter implanted extraperitoneally between the abdominal muscles. The EMG signals were collected by a receiver, filtered, amplified and archived by a computer. The telemetric EMG signal did not differ from that obtained with a conventional wire method. Substantial differences between day and night migrating myoelectric complex (MMC) patterns were found. The advantages of telemetric EMG recording make it a useful tool for long-term recording of antroduodenal EMG.
