Seizures terminable and interminable with ECT

The authors discuss the incidence, detection, management, and significance of prolonged seizures with ECT and present a case example. They suggest that the incidence of this phenomenon may be underreported and that its occurrence may be linked to hyperoxygenation, the use of multiple-monitored ECT, and preexisting states of cerebral hyperexcitability. Since prolonged seizures may result in adverse metabolic changes, prompt detection and intervention are essential.
