Abstract
Positioning of the dispersive electrode has no significant effect duri ng radiofrequency ablation, Doubling the surface area of the dispersiv e electrode results in a lower impedance, higher current delivery, and increased tip temperatures, particularly if the baseline impedance is > 100 Omega. These findings may have important implications for optim izing radiofrequency energy delivery using currently available radiofr equency generators.
