Abstract
Although it is often relatively easy for the clinician to differentiate between the heart and the esophagus as sources of chest pain, there remains a substantial minority of patients in whom this task is difficult. We have attempted to review points of differential significance which can be elicited through assessment of the patient's symptoms. Diagnostic studies for the detection of esophageal disorders have been reviewed, and the relative usefulness of these studies has been emphasized. As the result of advancements in diagnostic techniques as well as better understanding of esophageal pathophysiology, the clinician is now capable of accurately identifying the esophagus as the source of chest pain.
