EEG monitored ECT.

EEG monitored ECT was administrated to 20 patients, 12 females and 8 males. One hundred and fifty-six treatments were given (mean 7.8 treatments/patient), and the relation between clinically observed seizures (COS) and the cerebral patterns of convulsions (EPC) was compared. If clinical observation alone had been used, restimulation would have been necessary in 43 per cent of the treatments, whereas restimulation actually was done in 9 per cent. Similarly, too violent convulsion patterns would have been ignored in 5 per cent of the treatments.
