2. Single factor analysis of clinical data and echocardiographic parameters in the modeling group
Univariate logistic analysis showed that, after radiofrequency ablation, the age, left atrial diameter (LAD), mild MR, moderate MR, and severe MR in the recurrence group were all higher than those in the sinus rhythm group, and LAAV was lower in the recurrence group. The other parameters were not significantly different between the two groups (P >0.05, Table 3).
