Hypertension, Hypertensive Heart Disease
Renal Sympathetic Denervation Prevents Atrial Fibrillation in Patients With Hypertensive Heart Disease: a Pilot Study
The autonomic nervous system plays an important role in the precipitation of AF in structurally-abnormal hearts. Restoration of autonomic imbalance may therefore prevent new-onset AF.
