Data derived from standard resting 12-lead electrocardiogram (ECG) with the participant supine. Records were interpreted and Minnesota (MN) codes were provided by clinical cardiologists.

Incident Atrial Fibrillation (AF) after SHHS Visit 1

afibincident under Clinical Data/Incident Outcomes/Cardiovascular Diseases in SHHS variables

Variable created as part of the analysis for Tung et al. 2017 (PubMed ID: 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.
