Abstract:
Positioning of the dispersive electrode has no significant effect during radiofrequency ablation. Doubling the surface are of the dispersive electrode results in a lower impedance, higher current delivery, and increased tip temperatures, particularly if the baseline impedance is >100 ohms. These findings may have important implications for optimizing radiofrequency energy delivery using currently available radiofrequency generators.
