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 (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. |

|
Prevalent Atrial Fibrillation (AF) at SHHS Visit 1
Variable created as part of the analysis for Tung et al. 2017 (PubMed ID: 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. |
