title: [Simulated epileptiform discharges during the replay of a lengthy EEG recording].
abstract: Reviewing a longterm-EEG magnet-recording on the video system of the play-back unit "Mobile Oxford Medilog 9000" EEG patterns appeared, which imposed as epileptiform discharges. They seemed to correlate with the paroxysmal clinical disturbances the patient had experienced and noted in a diary, and could be printed out on a normal EEG-apparatus. Following investigations demonstrated the artificial origin of this EEG patterns: They appeared in fact only using the switches of the play-back unit for the fast back- and forward winding. The time-correlation between clinical and electroencephalographic episodes was simulated by the search of selected EEG-sequences based on the clinical episodes noted from the patient.
