3.3 Procedure characteristics
The procedural characteristics of the patients in the LRAF and non-LRAF groups are shown in Table 2. The ratio of cavo-tricuspid isthmus block, superior vena cava isolation, and left atrium posterior wall isolation did not differ significantly between the two groups. The ratio of a non-PV trigger ablation and atrial tachycardia ablation was significantly higher in the LRAF group than non-LRAF group (p<0.001, p=0.021, respectively)
