isoelectric electroencephalogram

e·lec·tro·ce·re·bral si·lence (ECS),

(ē-lek'trō-sĕ-rē'brăl sī'lens),

Flat or isoelectric encephalogram; an electroencephalogram with absence of cerebral activity over 2 mcv from symmetrically placed electrode pairs 10 (or more) cm apart, and with interelectrode resistance between 100-10,000 ohms; if such a record is present for 30 minutes in a clinically brain dead adult and if drug intoxication, hypothermia, and recent hypotension have been excluded, the diagnosis of cerebral death is supported.

Synonym(s): electrocerebral inactivity, flat electroencephalogram, isoelectric electroencephalogram
