Tertiary esophageal contractions evoked by acoustical stimuli.

Abstract

"Spontaneous" tertiary esophageal contractions occur in a high proportion of healthy subjects. This study was carried out to investigate whether such contractions can be elicited by acoustical stimuli, to determine the threshold intensity at which contractions occur, and to find out how many of a sequence of equiintense tones at such a threshold intensity… (More)
