Although linked to cardiovascular abnormalities, its relationship with atrial arrhythmia remains unclear. This study aimed to investigate the association between SBS and non\u2010pulmonary vein (PV)\u2010related atrial tachyarrhythmias (ATAs) in patients with atrial fibrillation (AF).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively analyzed 222 consecutive patients (mean age, 65.8 \u00b1 11.3 years) who underwent initial AF ablation. Following PV isolation, ATAs were induced and assessed using intracardiac electrocardiography. SBS was diagnosed by chest radiography and thoracic computed tomography. Twenty\u2010seven patients were classified into the SBS group, and 195 into the control group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Compared with controls, the SBS group had a lower body mass index, smaller left atrial diameter, and lower prevalence of hypertension and diabetes. Non\u2010PV\u2010related ATAs were more frequently induced in the SBS group (18\/27\u00a0vs. 50\/195,\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.01), including non\u2010PV\u2010triggered AF (7\/27\u00a0vs. 16\/195,\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.01), cavotricuspid isthmus\u2013dependent flutter (8\/27\u00a0vs. 17\/195,\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.01), and other atrial tachycardias (15\/27\u00a0vs. 33\/195,\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.01).
