Objective: Little is known about the (peri-) ictal changes in autonomic nervous system activity of epileptic
seizures. Such information may be useful for seizure prediction paradigms and differential diagnosis between
epilepsy and psychogenic non-epileptic seizures (PNES). The current study investigated the peri-ictal time course of
heart rate variability (HRV) measures, which reflect autonomic nervous system functioning.
Methods: HRV measures were extracted from electrocardiography data collected during 1-7 days of videoelectroencephalography
monitoring of 17 patients with epilepsy and 20 patients with PNES. Heart rate (HR) and
HRV measures (standard deviation of average beat-to-beat intervals (SDANN), root mean square of successive
differences (RMSSD), high frequency (HF) power, low frequency (LF) power and very low frequency (VLF) po.. View More»
