Abstract
A method and system in electroconvulsive therapy (ECT) to automatically monitor and display the occurrence and the duration of the seizure activity generated during the administration of the electrically induced therapeutic seizures. The ECT device includes a special-purpose electroencephalograph (EEG) system to detect a specific EEG parameter (e.g. integrated voltage) of the electrically induced EEG seizure. The detected integrated voltage is converted to digital data and compared to a threshold reference value previously obtained from the same patient. The operator is informed by an electronic alphanumeric elapsed time display or indications on a moving strip chart paper record, or oscilloscope CRT screen, when the parameter has crossed the predetermined threshold reference value and how long since the termination of the ECT the parameter has taken to reach the reference value.
