Introduction

Atrial fibrillation (AF) is the most frequent supraventricular arrhythmia but despite this its electrophysiologic substrate is still not completely known as well as its clinical significance in the different clinical situations due to few studies on atrial activation during AF in humans^1-5. Aim of this study was to evaluate the atrial activation during AF with an extensive mapping of the electrical excitation of the atria during AF.
