FIELD: medicine.
SUBSTANCE: gastroesophageal reflux disease is diagnosed by measuring gastric electrical activity (EA), gastric rhythm coefficient (Kritm) and gastric/duodenal comparison coefficient (CC), 24-hour oesophageal pH-metry, nitrogen oxide (nitrate/nitrite ratio). If the gastric EA is more than 23.2±4.1%, gastric Kritm is more than 5.43±2.2, gastric/duodenal CC is more than 11.2±5.6, acid reflux number is more than fifty a day and more, nitrogen oxide is less than 35.2±2.7 mcmole/l, gastroesophageal reflux disease is diagnosed.
EFFECT: technique enables increasing the diagnostic accuracy of gastroesophageal reflux disease, including in its endoscopically negative form.
