Polysomnography (PSG) Scoring Notes (Sleep Heart Health Study Visit One (SHHS1)): Intervening period bad EEG

restan4 under Sleep Monitoring/Polysomnography/Signal Quality/SHHS1 in SHHS variables

"1: Yes", this indicates more than 30 minutes of the sleep period had either lost or unscorable EEG data

Polysomnography (PSG) Quality Assessment : Abnormal EEG

abnoreeg under Sleep Monitoring/Polysomnography/Signal Quality in SHHS variables

Scorer observed abnormal EEG during study.

Abnormal EEG background / waveforms

1=Unusual Occurrences - Abnormal EEG

Scoring stage2/ deep sleep unreliable

stg2stg3pr under Sleep Monitoring/Polysomnography/Signal Quality in CHAT variables

1=sleep staging problem - scoring stage2/stage3-4 unreliable (when distinction between Stage 2 and Deep Sleep is unreliable because of EEG artifact (usually due to the respiratory or sweat artifact on the EEG, and High Pass filter =1Hz used))
