Epileptic seizure behaviour from the perspective of Heart Rate Variability

Heart Rate Variability (HRV) analysis has gained much importance in recent years, as a technique to explore the activity of autonomic nervous system (ANS), and an important early marker for identifying different pathological conditions. Epilepsy is a disease which progressively involves cardiac autonomic activity. Our studies indicate that time domain, frequency domain and some nonlinear measures of HRV would be able to provide valuable information regarding the autonomic dysfunction due to epileptic seizures. In this paper, we investigate the extracted features of heart rate variability for epileptic seizure detection and anticipation.
