Meta Analysis
Autonomic functioning in irritable bowel syndrome measured by heart rate variability: a meta-analysis.
To analyze autonomic functioning which presented as the high frequency (HF) component of heart rate variability, a measurement of vagal tone, and the ratio of low frequency (LF) to HF (LF : HF), an indicator of sympathovagal balance in irritable bowel syndrome (IBS) patients. ⋯ Impaired parasympathetic functioning and abnormal sympathovagal balance may be involved in the pathogenesis of IBS. Vagal dysfunction is more obvious in the IBS-C subgroup.
