Methods
Thirty-six AF patients who underwent an initial SVCI were enrolled.
Ablation was performed at a total of 549 points. The sites where dormant
conduction was induced or additional ablation was needed were defined as
touch-up sites (n=36). We compared the energy deliver time, power, CF,
Force-Time Integral (FTI), and AI between the touch up sites and control
sites (n=513).
