Autonomic nervous system control of the heart is a dynamic process in both health and
disease. A multilevel neural network is responsible for control of chronotropy, lusitropy …

The autonomic nervous system plays an important role in the modulation of cardiac
electrophysiology and arrhythmogenesis. Decades of research has contributed to a better …

Autonomic nervous system activation can induce significant and heterogeneous changes of
atrial electrophysiology and induce atrial tachyarrhythmias, including atrial tachycardia and …

Atrial fibrillation (AF) is an arrhythmia that can occur as the result of numerous different
pathophysiological processes in the atria. Some aspects of the morphological and …

A cardiac arrhythmia simply defined is a variation from the normal heart rate and/or rhythm
that is not physiologically justified. Recent years have witnessed important advances in our …

Cardiac arrhythmias are a leading cause of cardiovascular death. It has long been accepted
that life-threatening cardiac arrhythmias (ventricular tachycardia, ventricular fibrillation, and …

The National Heart, Lung, and Blood Institute convened an expert panel April 28 to 29,
2008, to identify gaps and recommend research strategies to prevent atrial fibrillation (AF) …

Atrial fibrillation is the most common sustained arrhythmia and is associated with significant
morbidity and mortality. The autonomic nervous system has a significant role in the milieu …

Background—The relationship between autonomic activation and the mechanisms of
paroxysmal atrial fibrillation remains unclear. Methods and Results—We implanted a …

Atrial fibrillation (AF) contributes to morbidity and mortality of millions of individuals. Its
molecular, cellular, neurohumoral, and hemodynamic pathophysiological mechanisms are …
