title: Oesophageal acid perfusion test as a complement to work test in patients with chest pain.
abstract: Out of 121 patients referred to a work test on account of chest pain, 67 with a case history typical for oesophageal dysfunction have been further investigated with an acid perfusion test during continuous ECG monitoring. Neither arrhythmias nor ST-T changes were induced by the procedure. Of the 67 patients, 6 had a "positive related" acid perfusion test, 23 a "positive unrelated" and the remainder a negative test. Five of the 14 patients with pathological effort ECG belonged to the group with a positive acid perfusion test. The acid perfusion test, as a safe routine in close connection with the effort ECG in selected patients, is a useful technique for establishing whether or not the patient's symptoms have an oesophageal component.
