Methodological issues in the spectral analysis of the heart rate variability: Application in patients with epilepsy
Heart rate variability (HRV) is a useful measure of autonomic function. Frequency domain analysis of HRV in 68patients with epilepsy was performed. Two-parametric and two non-parametric spectral methods were employed. Epilepsy-related abnormalities of HRV were not consistent in all four methods. Parametric methods seemed to be more appropriate for this type of analysis.
