Experimental studies of atrial fibrillation: a comparison of

the atrial substrate and AF vulnerability and to evaluate ther-apies for AF, multiple animal models of AF have been devel-oped. They include sterile pericarditis, acute atrial ischemia, atrial volume overload, mitral regurgitation, pacemaker-induced atrial tachycardia, and ventricular pacing-induced heart failure (25).

Substrate Modification is a Better Predictor of Catheter

Atrial fibrillation (AF) is estimated to currently affect 5 million Americans and 6 million Europeans, and its preva-lence is expected to increase over the next three decades.1,2 The mechanisms underlying the initiation and maintenance of this arrhythmia have been studied in humans as well as

These parameters can be influenced by various physical factors (e.g., body posi - tion and respiration). In an experimental study, Bricker

Thus, in addition to the internal noise introduced by the record-ing systems as well as common baseline wandering from patient s respiration, other disturbances from muscular ac-

The cardiac ANS can modulate atrial electrophysiological prop-erties and facilitate both initiation and maintenance of atrial arrhythmias [1].

Phase 1: Atrial Contraction Represented by the P-wave of the electrocardiogram, it is characterized by electrical depolarization of the atria. An AP fires at the SA node leading to atrial depolarization, which initiates contraction of the muscle of the atria and pressure within the atrial chambers consequently increases.
