[The significance of EMG artefacts in isoelectric EEG].
Five potential organ donors showed muscle artefacts during isoelectrical EEG recording. The electromyographic examination revealed MUAP activity occurring as doublets, triplets and quadruplets. All patients had normal blood chemistry except reduced CO2 and increased O2 partial pressures. We assume that the recorded "tetaniform" muscle activity is due to hyperexcitability of the nerve membrane caused by artificial hyperventilation.
