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 suppression of normal activity with bitemporal ECT, but with unilateral non-dominant hemisphere ECT there is less suppression of normal activity in the unstimulated side.
电休克治疗（ECT）诱发的癫痫电活动呈现三个阶段：第一阶段为初始的18 - 22赫兹（类似β波）活动，第二阶段为无节律的多棘波活动，第三阶段为节律性的2.5 - 3.5赫兹棘波/多棘波 - 慢波活动。采用双侧颞部ECT时，第二阶段活动在所有导联同时出现。采用单侧非优势半球ECT时，第二阶段的多棘波从右前颞区呈有序进展。癫痫发作终止后，双侧颞部ECT会对称抑制正常活动，但单侧非优势半球ECT对未受刺激侧正常活动的抑制较少。
