However, some patients with paroxysmal AF (PAF) may be assigned by AI\u2010ECG to lower AF likelihood categories. Clinical and echocardiographic characteristics associated with AF likelihood assignment by AI\u2010ECG remain unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This single\u2010center prospective study enrolled adults with documented PAF admitted for catheter ablation who were in sinus rhythm on the admission ECG. The four AF likelihood categories output by AI\u2010ECG were dichotomized into higher and lower groups for analysis. Logistic regression was used to assess factors associated with assignment by AI\u2010ECG to the higher AF likelihood group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 104 patients, 36 were categorized into the lower and 68 into the higher AF likelihood group. Hypertension was associated with lower odds of higher\u2010group assignment (odds ratio [OR], 0.25; 95% confidence interval [CI], 0.10\u20130.66).

Hypertension and higher LVMI were inversely associated with assignment to the higher AF likelihood group, whereas mild or greater TR showed a possible positive association. These findings suggest that AI\u2010ECG\u2010based AF likelihood assignment varies among patients with documented PAF during sinus rhythm.<\/jats:p>\n
