Autonomic function in patients with migraine : a quantitative study by spectral analysis of heart rate variability / 临床神经病学杂志

Using a spectral analysis of heart rate variability (SAHRV) in supine and standing positions were performed in a group of 65 patients with migraine and in a control group of 50 healthy volunteers in order to quantitative evaluate the function of autonomic nervous system(ANS). The result revealed that the integrals of middle frequency bands of amplitude spectra of standing patients were smaller than that of controls (P
