Ect Induced Eeg Seizure: Validity of Duration Estimation by Last Spike
نویسندگان
چکیده
The seizure EEG records of 25 depressives receiving ECT were 'blindly' rated by two trained raters using a uniform definition of seizure endpoint. The EEG seizure duration estimates were validated against five expected relationships. EEG seizure duration correlated with and was more than motor seizure duration, reduced over the course of ECTs, was consistent within subjects, and negatively varied with age. Within clinical constraints, the method of seizure duration estimation by the last spike is valid.

Seizure Duration Estimates from Single Channel Eeg Record: a Methodological Report
Seizure duration was estimated using a single channel EEG recording during ECT. Seizure endpoint was defined as the point of last spike. Three psychiatrists independently rated forty seven EEG records. Seizure endpoint could be reliably identified. The reliability coefficient between three raters was 0. 92, indicating high agreement among raters. Modal difference between any pair of raters as w...

The duration of the motor seizure was examined next, and in evaluations of the seizures in unilateral and bilateral ECT, it seemed reasonable to opine that a minimum of 25 seconds defined a good seizure (Fink and Johnson, 1982). In studies of unilateral and bilateral ECT with threshold and suprathresh-old energy dosing, motor seizure durations were greater than 25 seconds, yet the threshold-uni...
