Role of the Autonomic Nervous System in Atrial Fibrillation

[Atrial fibrillation and the autonomic nervous system].

The autonomic nervous system plays an important role in the genesis of various cardiac rhythm disorders. Experimental studies have indicated that in atrial fibrillation particularly vagal activity may have a decisive influence on the electrophysiologic properties of atrial myocardium. In patients with paroxysmal atrial fibrillation, a carefully taken history and electrocardiographic findings ob...

The Intrinsic Autonomic Nervous System in Atrial Fibrillation: A Review

The procedure of catheter ablation for the treatment of drug resistant atrial fibrillation (AF) has evolved but still relies on lesion sets intended to isolate areas of focal firing, mainly the myocardial sleeves of the pulmonary veins (PVs), from the rest of the atria. However the success rates for this procedure have varied inversely with the type of AF. At best success rates have been 20 to ...

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.

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...

Role of atrial electrophysiology and autonomic nervous system in patients with supraventricular tachycardia and paroxysmal atrial fibrillation.

OBJECTIVES The purposes of this study were to evaluate the atrial electrophysiology and autonomic nervous system in patients who had paroxysmal supraventricular tachycardia (PSVT) associated with paroxysmal atrial fibrillation (PAF). BACKGROUND PAF frequently appeared in patients with PSVT. However, the critical determinants for the occurrence of PAF were not clear. METHODS This study popul...
