AF, atrial fibrillation; LAD, left atrial anteroposterior diameter; LVEDD, left ventricle end-diastolic diameter; LVESD, left ventricle end-systolic diameter; LVEF, left ventricle ejection fraction.
aP-value: control group vs. lone AF sport group.
bP-value: lone AF sport group vs. lone AF (without history of sport practice) group.
