May warrant caution interpreting esophageal contractions in noncardiac chest pain; leaves open need to redefine normal motility criteria.

A newly developed 24-hour ambulatory esophageal pressure monitor revealed a high incidence of 'abnormal' contractions in normal subjects, which may impact the evaluation of noncardiac chest pain.
Pfister et al. (1989) conducted an observational in Healthy volunteers (n=10). 24-h ambulatory esophageal pressure monitor was evaluated on Incidence of abnormal esophageal contractions. Testing of a newly developed 24-hour ambulatory esophageal pressure monitor in 10 normal subjects revealed a relatively high incidence of contractions typically considered abnormal.
