Autonomic Response to a Visceral Stressor is Dysregulated in Irritable Bowel Syndrome and Correlates with Duration of Disease

摘要

BackgroundPrevious studies reported altered autonomic nervous system (ANS) responses in IBS at baseline and to colonic balloon distension. This study examined heart rate variability (HRV) and plasma catecholamines as an index of ANS responsiveness in IBS during flexible sigmoidoscopy (FS) and explored associations of HRV with clinical measures.
