Heartburn correlated to 24-hour pH monitoring and radiographic examination of the esophagus.

Abstract

(1) pHM findings did not correlate with presence or absence of HB; (2) pHM is usually normal in patients with normal esophagus on RE; (3) pHM is also usually normal in patients with HB and normal esophagus on RE; and (4) pHM is often normal in patients with radiographic findings of reflux esophagitis or peptic stricture.
