Figure 7

The Kaplan‐Meier curve comparing AT/AFL/AF free survival after AF ablation. (A) Among AF patients with fixed C-EGMs, fixed C-EGMs ablation significantly decreased incidence of recurrence compared with linear ablation (HR: 0.43; 95% CI 0.21‐0.81; P = 0.011 by log‐rank test). (B) In AF patients receiving linear ablation, patients without fixed C-EGMs were associated with a lower relative risk for recurrence (HR: 0.41, 95% CI 0.20–0.79, P = 0.009 by log‐rank test). AF, atrial fibrillation; AFL, atrial flutter; AT, atrial tachyarrhythmia; C-EGMs, complex electrograms in sinus rhythm; CI, confidence interval; HR, hazard ratio.
