Baseline characteristics
GROUP B
A total of 62 patients with atypical AVNRT were studied. Group A (n = 30, 15 male, age 54 ± 11.7 years) were treated with “conventional ablation” at the anatomic area of the slow pathway. Group B (n = 32, 13 male, age 55 ± 12.2 years) were treated with ablation 2 mm higher in the septum. There were no significant differences in age and sex between the two groups (P = 0.51 and P = 0.43, respectively).
