Intra-atrial pressure increases rate and organization of waves emanating from the superior pulmonary veins during atrial fibrillation

Atrial fibrillation (AF) commonly associates with atrial dilatation by poorly understood mechanisms. We hypothesized that elevation of intra-atrial pressure elicits high-frequency and spatio-temporally organized left atrial (LA) sources emanating from the superior pulmonary veins. We used a stretch-...
