Kaplan-Meier event-free survival analysis for the cumulative freedom from AF /AT recurrence.
A. The atrial arrythmia freedom off anti-arrhythmic drugs after the PVI was significantly lower in the patients with high-DFs sites ≧7Hz overlapping with LVAs than in those without during 11.6±0.8 months of follow-up (35.7% vs. 69.5%, p=0.008). B. There was no significant difference in the %NP sites ≧50% overlapping with LVAs between the two groups.
