Pressure profile of esophageal peristalsis in normal humans as measured by direct intraesophageal transducers

Abstract
The pressure profile of esophageal peristalsis was studied in healthy young adult males using an intraesophageal transducer assembly. The amplitude of peristaltic contractions following wet swallows was determined at intervals along the esophagus from the lower esophageal sphincter (LES) to the upper esophageal sphincter (UES). The amplitude profile revealed a trough of significantly decreased (Pdp/dt) produced a profile also with a significant decrease (Pr=0.91,PPPdp/dt) is also described, and its possible importance discussed.
