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 …

Cardiac arrhythmias are prevalent among humans across all age ranges and may occur in
the setting of underlying heart disease as well as in structurally normal hearts. While …

The Japanese Circulation Society (JCS) published the “Guidelines for Pharmacological
Treatment of Arrhythmia” in 2004, and a revised edition was published in 2009. 1 Both …

Background—The transition from persistent to permanent atrial fibrillation (AF) is associated
with increased complexity of fibrillatory conduction. We have investigated the spatial …

The autonomic nervous system (ANS) has a significant influence on the structural integrity
and electrical conductivity of the atria. Aberrant activation of the sympathetic nervous system …

Aims Atrial fibrosis contributes to arrhythmogenesis in atrial fibrillation and can be detected
by MRI or electrophysiological mapping. The current study compares the spatial correlation …

Background—Over a time course of months, the stability of atrial fibrillation (AF) gradually
increases and the efficacy of pharmacological cardioversion declines both in humans and in …

The most common sustained cardiac arrhythmias in humans are atrial tachyarrhythmias,
mainly atrial fibrillation. Areas of complex fractionated atrial electrograms and high dominant …

BACKGROUND: Temporal variation in complex fractionated atrial electrograms (CFAEs)
exists during atrial fibrillation (AF). OBJECTIVE: This study sought to quantify the variation in …
