Values are or medians with 25th and 75th percentiles and frequencies (percentages). AF: atrial fibrillation; BMI: body mass index; OSAHS: obstructive sleep apnea-hypopnea syndrome; SHD: structural heart disease; LA: left atrium; LVEF: left ventricular eject fraction; NOACs: non-vitamin K antagonist oral anticoagulants; AADs: antiarrhythmic drugs.
