Pericardial fat is independently associated with human atrial fibrillation.

Objectives: The purpose of this study was to investigate the association between atrial fibrillation (AF) and pericardial fat.

Background: Pericardial fat is visceral adipose tissue that possesses inflammatory properties. Inflammation and obesity are associated with AF, but the relationship between AF and pericardial fat is unknown.

Catheter ablation of supraventricular arrhythmias and atrial fibrillation.

Supraventricular arrhythmias are relatively common, often persistent, and rarely life-threatening cardiac rhythm disturbances that arise from the sinus node, atrial tissue, or junctional sites between the atria and ventricles. The term "supraventricular arrhythmia" most often is used to refer to supraventricular tachycardias and atrial flutter. The term "supraventricular tachycardia" commonly refers to atrial tachycardia, atrioventricular nodal reentrant tachycardia, and atrioventricular reciprocating tachycardia, an entity that includes Wolff-Parkinson-White syndrome.
