Electrogastrography- A Non-Invasive technique

Abstract

EGG is abnormal, it confirms that the problem probably is with the stomach’s muscles or the nerves that control the muscles. EGG is a non-invasive method for the recording of gastric myoelectrical activity that controls gastric motility. Abnormality in EGG arises due to recurrent nausea, vomiting, dyspepsia, stomach ulcer, cyclic vomiting syndrome, etc which signals that the stomach is not emptying food normally. If the EGG is similar to an electrocardiogram of the heart. It is the recording of the electrical signals that travel through the muscles of the stomach and control the muscle’s contraction. EGG used when there is a suspicion that the muscles of the stomach or the nerves controlling the muscles are not working normally. Recording is done by placing the electrode cutaneously over the stomach and the electrical signals from the stomach’s muscles are sensed by the electrode and recorded on a computer for analysis. In normal individuals, EGG is a regular electrical rhythm generated by the muscles of the stomach and the strength of the electrical current increases after the meal. In patients with abnormalities of the muscles or nerves of the stomach, the rhythm often is irregular or there is no post-meal increase in electric power.
