One of the cases of our ablation protocol (nonblock type). A, We set the first lower threshold of 22 (%). RF application is delivered to the area where the white line does not appear but the SVC is not isolated. B, The lower threshold is 5% and increases to 27%, and a new gap appears. RF application is delivered to the new gap but the SVC is not isolated. C, The lower threshold is 5% and increases to 32%, SVC isolation is successfully achieved through the additional ablation to the new gap
