Figure 2: The change in the intracardiac defibrillation
threshold before and after RFCA
There was no difference in the IDF threshold between the no-recurrence
group and recurrence group before the RFCA, however, the threshold in
the no-recurrence group was significantly lower than that in the
recurrence group after the RFCA. The red colored line and words show the
recurrence group, and the black colored lines and words show the no
recurrence group. RFCA = radiofrequency catheter ablation, IDF =
Intracardiac defibrillation
Figure 3: The ROC curve for recurrence and intracardiac
defibrillation threshold after RFCA
Cut-off point analysis show that an intracardiac defibrillation
threshold after the RFCA of > 5J was the optimal point that
discriminated those with AF recurrence from the rest of the participants
(sensitivity 68.0% and specificity 65.2%).

Kaplan-Meier survival analysis for long-term sinus rhythm maintenance
after RFCA.
Patients with an intracardiac defibrillation threshold after the RFCA of
> 5J had a higher risk of recurrence than those with an
intracardiac defibrillation threshold after the RFCA of ≤ 5J.
