Overview

Electrode type may influence ablation impulse delivery in vitro; leaves open whether active fixation improves clinical outcomes.

Structured PICO

Does the type of pacing electrode affect the physical properties of high-energy electrical impulses during ablation in an in vitro model?

Population

In vitro model using three U.S.C.I. bipolar electrodes and three Vitatron Helifix electrodes immersed in Ringer's solution

Intervention

Unipolar electrical impulses of 10 to 400 joules

Comparator

Comparison between U.S.C.I. bipolar electrodes and Vitatron Helifix electrodes

Outcome

Physical effects including flash shapes, 'fire-ball' diameter, pressure, voltage, and currentsurrogate

In vitro testing of ablation electrodes demonstrates that active fixation electrodes may be more effective with lower energy impulses compared to standard bipolar electrodes.
