Healthy Clinical Trial
Official title:
Effects of Transauricular Vagal Nerve Stimulation on Electrogastrography (EGG) and Heart Rate Variability (HRV) in Healthy Subjects, Functional Dyspepsia, and Gastroparesis
The goal of this study is to establish parameters of gastric myoelectrical activity and heart rate variability in healthy human subjects and compare and contrast them to those with gastroparesis and functional dyspepsia, at baseline and following taVNS.
This is a prospective pilot study assessing the relationship of electrogastrography and heart rate variability, with transauricular stimulation of the vagal nerve in healthy subjects compared to gastroparesis and functional dyspepsia patients. The investigators plan to recruit a total of 60 patients: 20 healthy volunteers, 20 gastroparesis, and 20 functional dyspepsia patients. Participants will undergo two testing sessions in which electrogastrography (EGG) and heart rate variability (HRV) will be measured using electrodes following transauricular vagal nerve stimulation (tAVNS) at various frequencies. ;
