R = Right Hemisphere, L = Left Hemisphere, BL = Bilateral N.A.= Data not available * No clear definition of heart rate change is provided # 39 of the seizures were frontal lobe, 3 of occipital and 4 of parietal lobe origin, lateralisation was not stated. Tachycardia is defined as an increase of 10 bpm or more. Bradycardia is defined as a decrease of 10 bpm or more.
