ABSTRACT |
Objectives: The aim of this study was to investigate the evaluation of gastrointestinal parasympathetic nerve activity by comparing between HRV and bowel sound parameters in patients with functional dyspepsia.
Methods : 62 patients (male 22, female 40) were enrolled. HRV was measured in all patients, and TP (total power), LF (low frequency density: 0.04∼0.15Hz), HF (high frequency density: 0.15∼0.4Hz), and LF/HF ratio were analyzed. HF band is a reflection of parasympathetic activity, and the LF-to-HF ratio is considered a marker of sympathovagal balance. Bowel sounds were recorded at the day after, and postprandial %BS was used to indicate the gastric vagal activity after eating. HRV and bowel sound parameters were compared, and correlation between them was analyzed.
Results: There was no difference in LF/HF ratio between patient group and healthy group of other report. According to values of %BS, each patient was classified into a normal (>6 %BS) or hypoactivity (<6 %BS) of gastric vagus nerve group. HF component of the hypoactivity group was not significantly higher than that of the normal group. There was no correlation between HRV and bowel sound parameters.
Conclusions: Because no correlation was found between HRV and bowel sound parameters in patients with functional dyspepsia, we concluded that it is not proper to evaluate gastric vagus nerve activity by HRV measurement. |
