Role of the autonomic nervous system in atrial fibrillation: pathophysiology and therapy.

Autonomic nervous system activation can induce significant and heterogeneous changes of atrial electrophysiology and induce atrial tachyarrhythmias, including atrial tachycardia and atrial fibrillation (AF). The importance of the autonomic nervous system in atrial arrhythmogenesis is also supported by circadian variation in the incidence of symptomatic AF in humans. Methods that reduce autonomi...

Recent insights into the role of the autonomic nervous system in the creation of substrate for atrial fibrillation: implications for therapies targeting the atrial autonomic nervous system.

Effect of Yoga on the Autonomic Nervous System: Clinical Implications in the Management of Atrial Fibrillation

Atrial fibrillation (AF), the most common sustained cardiac arrhythmia, is seen in approximately 1.5% of the U.S. population [1] and results in substantial morbidity and mortality [2]. One of the largest U.S. epidemiological studies, the Framingham Heart Study, predicted that AF prevalence doubles with each advancing decade of age, from 0.5% at age 50-59 years to almost 9% at age 80-89 years, i...

Heart rate variability and early recurrence of atrial fibrillation after electrical cardioversion.

OBJECTIVES The study evaluated the role of the autonomic nervous system in atrial fibrillation (AF) recurrence. BACKGROUND Early recurrence of AF after cardioversion (CV) is attributed to electrical remodeling. The possibility that an abnormal autonomic modulation might contribute to this phenomenon has not yet been adequately tested. METHODS We analyzed short-term heart rate variability (H...

Autonomic Denervation for the Treatment of Atrial Fibrillation

The influence of the autonomic nervous system (ANS) on triggering and perpetuation of atrial fibrillation (AF) is well established. Ganglionated plexi (GP) ablation achieves autonomic denervation by affecting both the parasympathetic and sympathetic components of the ANS. An anatomic approach for GP ablation at relevant atrial sites appears to be safe, and improves the results of PV isolation i...

Increase of Autonomic Nerve Factors in Epicardial Ganglionated Plexi During Rapid Atrial Pacing Induced Acute Atrial Fibrillation

BACKGROUND The cardiac autonomic nervous system plays an essential role in epicardial ganglionated plexi (GP) regulation of atrial fibrillation onset and progression. To date, the activity of GP and the function of the cardiac autonomic nervous system are not well understood. The aim of this study was to determine alterations in epicardial GP cholinergic nerve, adrenergic nerve, and nerve growt...
