[Automatic recognition of spike-wave discharges in dynamic EEG].
A computerized system for automatic recognition of spike and wave discharges (SWDs), recorded by ambulatory EEG, is described. Four parameters were sequentially considered for detecting SWDs: amplitude, frequency, rhythmicity and second derivative of the EEG epochs to be evaluated. With this system the computer was able to recognize in 20 patients 95% +/- 4.7 of SWDs visually detected, while the percentage of the SWDs as compared with the total number of "discharges" found by the computer was 82.4% +/- 15.5.
