With the rapid evolution of atrial fibrillation ablation procedures, electrophysiologists
have necessarily strived for simple and anatomic-based approaches. In all except the
most straightforward procedures, however, questions regarding the significance of
various potentials recorded on mapping and ablation catheters arise.

Other articles in this series have described in detail the various approaches to
atrial fibrillation ablation. In this article, the anatomic and electrophysiologic
bases for pacing maneuvers used with a variety of ablation approaches are reviewed.
The primary focus is on understanding the pacing maneuvers relevant to pulmonary vein
(PV) isolation. These techniques, with some changes, can be applied to ablation of
the superior vena cava and vein of Marshall.Keywords
