In Japan, the distal limit of the lower esophageal palisade vessels is usually regarded as the EGJ and the designated area of the columnar-lined esophagus (CLE) is anatomically defined by the ...
With primary peristalsis, note that the delay in onset of depolarization, spike burst, and esophageal contraction in the distal esophagus relates to a marked secondary hyperpolarization (arrow).
