title: Postprandial variations in ST-segment in a patient with Brugada syndrome and partial gastrectomy.
abstract: A 74-year-old man with a history of partial gastrectomy presented with an electrocardiogram consistent with Brugada syndrome and marked meal related fluctuations in the ST segment. ST-segment elevation was prominently attenuated at 30 minutes and increased at 120 minutes after meals. Analysis of heart rate variability revealed a relationship between postprandial heightened parasympathetic activity and increase in Brugada-type ECG abnormality. A rapid postprandial increase in blood glucose may initially stimulate sympathetic nervous activity and secondarily increase parasympathetic tone. Food intake can be associated with fluctuations in ST-segment elevation in patients with the Brugada syndrome.
