electrical seizure activity induced by ECT appears in three phases: Phase I initial 18-22 Hz. (beta-like) activity, Phase II arrhythmic polyspike activity, and Phase III rhythmic 2 1/2-3 1/2 Hz. spike/polyspike-wave activity. With bitemporal ECT, Phase II activity appears simultaneously in all leads. With unilateral non-dominant hemisphere ECT, there is an orderly march on Phase II polyspikes from the right anterior temporal region. After termination of a seizure, there is symmetrical… CONTINUE READING
