IFCN standards for digital recording of clinical EEG

To ensure good quality digital EEG recording in clinical use, the following standards have been adopted for recording, storing, reviewing and exchanging EEGs among clinicians and laboratories. These standards are meant for digital EEG used in clinical patient care. They should not be used to constrain research use of EEG recordings. Digital recording gained popularity over analog EEGs because of several advantages. Digital recording takes advantage of modern microprocessor costs and general flexibility. More specifically, it allows EEG-record review with user-selected montages, filters, vertical scaling (gain or sensitivity) and horizontal scaling (e.g. time resolution or compression). It also replaces the need to warehouse or microfilm paper records, enables optional additional digital EEG-signal processing and allows for electronic exchange of EEGs.
