A287 REACTIVITY OF THE EXTRINSIC AUTONOMIC NERVOUS SYSTEM ASSOCIATED WITH HUMAN COLONIC MOTOR PATTERNS

The role of the autonomic nervous system (ANS) in control of colonic motility is unclear. Measurement of heart rate variability may provide diagnostic information for patients with colonic dysmotility. We explored relationships between the cardiac output of the ANS through heart rate variability (HRV) and colonic motor patterns with or without sensation during high-resolution colonic manometry (HRCM) Ten healthy volunteers (33 ± 12 yrs; 6 male)...
