Definition of Electrogastrogram
Electrogastrogram: An electrogastrogram is a study in which the electrical current generated by the muscle of the stomach is sensed and recorded. Thus, it is analogous to an electrocardiogram of the heart.
The electrogastrogram, like the electrocardiogram, is performed by taping electrodes to the skin; however, in the case of the electrogastrogram the electrodes are placed on the upper abdomen over the stomach. The recordings from the muscle are stored and analyzed by a computer.
The electrogastrogram is performed to diagnose motility disorders of the stomach, that is, when the muscles of the stomach are not working normally.
