Regional electrical differences and arrhythmia in the rat atria: Role of sympathetic nerve distribution and function.
Atrial fibrillation (AF) commonly arises in the left atrial posterior wall (LAPW) and pulmonary veins (PVs). Dysregulated atrial sympathetic control is a central mechanism driving the induction and maintenance of AF. However, regional differences in atrial sympathetic structure and function remain poorly characterised....
