The basal or basic electrical rhythm (BER) or electrical control activity (ECA) is the spontaneous depolarization and repolarization of pacemaker cells known as interstitial cells of Cajal (ICCs) in the smooth muscle of the stomach, small intestine, and large intestine.
Excessive insufflation of the stomach is avoided at this stage. The endoscope is quickly passed through the stomach and through the pylorus to examine the first and second parts of the duodenum . Once this has been completed, the endoscope is withdrawn into the stomach and a more thorough examination is performed including a J-maneuver.
