Interference suppression for EEG recording during open heart surgery.
A device for recording the EEG during open heart surgery is described. It differs from most standard equipment in two ways. First, the input circuit is completely floating from earth and will withstand 500 V DC. Second, radiofrequency (RF) shielding and filtering permits continuous recording of the EEG during electro-surgery in the operating room. The almost undisturbed recording permits on-line continuous EEG monitoring by means of quantitative signal analysis methods.
