afibincident
Incident Atrial Fibrillation (AF) after SHHS Visit 1
Incident Atrial Fibrillation (AF) after SHHS Visit 1

Variable created as part of the analysis for Tung et al. 2017 (PMID: 28668820). Incident AF was considered present if AF was identified on a 12-lead ECG obtained at the second SHHS exam or was adjudicated by the parent cohorts at any time between the baseline PSG and the final follow-up date for AF ascertainment of June 30, 2006.

Prevalent Atrial Fibrillation (AF) at SHHS Visit 1

Variable created as part of the analysis for Tung et al. 2017 (PMID: 28668820). Prevalent AF was defined by any of the following: a positive response to the question 'Has a doctor ever told you that you have or had atrial fibrillation'; AF identified on resting 12-lead ECG at the baseline SHHS exam; or if the parent study identified AF documented in the medical record before the SHHS baseline exam.

overall_shhs2
Polysomnography (PSG) Quality Assessment (Sleep Heart Health Study Visit Two (SHHS2)): Overall signal quality
Polysomnography (PSG) Quality Assessment (Sleep Heart Health Study Visit Two (SHHS2)): Overall signal quality

Overall study grade as assigned by scorer. These codes reflected the total duration of useable (artifact free, scorable) signals during sleep time across channels, weighing those signals most critical for accurate scoring of respiratory events and staging during sleep time. The Quality Assessment Form for SHHS2 was modified so that the overall quality grade and the signal quality codes were based on signals during sleep time. Since events were only scored during sleep time this provided a more accurate assessment of signal quality during the actual time or scoring. This change would only have affected the quality grade of a small number of studies in SHHS1 where there was a significant amount of time awake with very good signals combined with very poor signals that occurred during sleep. The overall and signal quality grades are comparable between SHHS1 and SHHS2.
