The Right Atrium Affects in silico Arrhythmia Vulnerability in Both Atria

The role of the right atrium (RA) in atrial fibrillation (AF) has long been overlooked. Multiple studies have examined clinical conditions associated with AF, such as atrial enlargement, fibrosis extent, electrical remodeling, and wall thickening, but have been mainly concentrated on the left atrium (LA). AF research predominantly focuses on the LA due to two key paradigms: Firstly, the well-established view that AF onset is primarly triggered by activity originating in the pulmonary veins (PVs) of the LA [1].
