Overview

The purpose of this study is to assess the electrophysiological mechanism of atrial fibrillation by means of a beat-to-beat noninvasive 3D mapping method in patients with concomitant persistent and long-standing persistent atrial fibrillation undergoing surgical ablation.

Outcomes

Primary Outcomes

The patients electrophysiological mapping results acquired with ECGI will be analyzed: Number and distribution of rotor and focal activities will be measured.

The primary objective of this study is to measure the patients electrophysiological mapping results acquired with ECGI, namely the number and distribution of focal and rotor activities.

Time frame: Prior to the planned procedure.
