摘要：Summary. - Right atrial (RA) mapping has been recently more carefully examined in patients with idiopathic
atrial fibrillation (AF) in order to improve radiofrequency (RF) catheter-mediated ablation lines to control
recurrences. The aim of this study was to map right atrial activation during AF to analyze relationship
between anatomy and atrial activation for specific sites. Twenty-four patients with recurrent, drug-refractory,
paroxysmal AF underwent an extensive mapping of the RA before attempting RF linear lesion catheter ablation.
A typical pattern of atrial activation was recorded in all patients which was consistent with a more regular
activity on the trabeculated right atrium (type I AF) and a more fragmented and complex activation on the
posterior and the anterior septum (type II and III AF). This paper helps to understand the influence of the
anatomic barriers to atrial activation during atrial fibrillation.
