Slow potentials of EEG burst suppression pattern during anaesthesia.
EEG burst suppression pattern was recorded during propofol and isoflurane anaesthesia. Using a long time constant, i.e. a high-pass filter with low cut-off frequency, revealed slow potentials, DC shifts, during bursts. These have been extensively studied in conjunction with cognitive-evoked potentials and epileptic discharges, but not previously in burst suppression EEG.
