Fig. 1From: Epilepsy in patients undergoing cardiac surgery with ExtraCorporeal Circulation: case series and description of a peculiar clinical phenotypePatients’ EEG. Figure 1 shows the EEGs of the four patients included in this case series. Patient 1 (A): the EEG during sleep (NAP) showed asynchronous spikes and slow waves both in right parieto-occipital derivations and in left fronto-temporal region (red circles). Patient 2 (B): a NAP EEG showed spikes during sleep in right fronto-central-temporal derivation, and independent slow and sharp waves in left fronto-temporal derivations (red circles). Patient 3 (C): NAP EEG revealed sharp waves in right parieto-occipital region and independent spikes localized in left fronto-temporal derivations (red circles). Patient 4 (D): the NAP EEG showed sharp waves and spikes in the left fronto-parietal derivations during drowsiness and sleep (red circles)Back to article page
