Dynamic electrophysiological mechanism in patients with long-standing persistent atrial fibrillation.

ABSTRACT:

Background

Improved understanding of the mechanisms that sustain persistent and long-standing persistent atrial fibrillation (LSpAF) is essential for providing better ablation solutions. The findings of traditional catheter-based electrophysiological studies can be impacted by the sedation required for these procedures. This is not required in non-invasive body-surface mapping (ECGI). ECGI allows for multiple mappings in the same patient at different times. This would expose potential electrophysiological changes over time, such as the location and stability of extra-pulmonary vein drivers and activation patterns in sustained AF.

Materials and methods

In this electrophysiological study, 10 open-heart surgery candidates with LSpAF, without previous ablation procedures (6 male
