Ambulatory Esophageal Manometry: Comparison of Expert and Computer‐Aided Analyses

This study describes the validation of a computer program for automated analysis of ambulatory 24‐hour two‐channel esophageal manometry. The program's ability to characterize contractions and to calculate their duration and amplitude was validated against manual evaluation. An independent reference standard for the identification and classification of contractions was established by submitting representative recordings to a group of 14 experts …
