Patient characteristics
Table 1 shows the patient characteristics at baseline in this study. The patients consisted of 68 males and 26 females (age range from 42 to 85 years, with a mean of 66 years). All SVC isolations were achieved successfully without any acute complications. Although 33% of the all patients were needed an additional application for the PN capture site, PN paralysis (PNP) was not observed after the procedure. At the one-month followup, two patients developed asymptomatic PNP, but both got recovered four months after the ablation procedure. Ectopic foci from SVC were observed in 13% of the patients.
