[The new cassette EEG recording system: its application to epileptic children].

We designed a new cassette EEG recording system which consists of a recording block (an ambulatory-type data recorder and a newly developed pre-amplifier) and a reproduction block (a fixed-type data recorder, a personal computer equipped with A/D converting board and an intervening EEG device for a bandpass filter). This system was applied to 36 epileptic children, and 33 ictal records were obtained. The seizure type could be precisely classified by a comparative analysis of the data computed from this system and from the ictal symptoms. Three representative cases were presented with actual analysis procedures.
