Photoplethysmography (PPG) reflects variations of blood perfusion in tissues, which may signify seizure‐related autonomic changes. The aim of this study is to assess the variability of PPG signals and their value in detecting peri‐ictal changes in patients with focal impaired awareness seizures (FIASs).
PPG data were recorded using a wearable sensor placed on the wrist or ankle of children with epilepsy admitted for long‐term video‐electroencephalographic monitoring. We analyzed PPG data in four different periods: seizure‐free, preictal, ictal, and postictal. Multiple features ...Seguir leyendo →
