Fibrillation is a hazardous phenomenon in cardiac muscle and so any new work towards the understanding of this process is important to the development of new methods in diagnosis and therapy. In this work we have used surface and intra cardiac ECGs of patients with chronic atrial fibrillation (AF). By means of the blind source separation (BSS) algorithm, which is a well-known method in signal p...
Patient Selection Criteria The use of transcatheter radiofrequency ablation (RFA) or cryoablation as a treatment for atrial fibrillation (AF) may be eligible for coverage for the following indications which have failed to respond to adequate trials of antiarrhythmic medications: Symptomatic paroxysmal or symptomatic persistent atrial fibrillation (AF); or As an alternative to atrioventricul...

Selecting appropriate treatment strategies for patients with persistent atrial fibrillation has often proved to be a quandary. Foregoing any debate on anticoagulant therapy, the remaining issue is whether the ultimate goal should be achieving and maintaining sinus rhythm or simply controlling the ventricular response during ongoing atrial fibrillation. Since atrial fibrillation affects 5% of th...
Introduction: Electrophysiological studies have demonstrated a relationship between aging and atrioventricular (AV) nodal conduction and refractoriness. The aim of the present study was to determine the effects of nodal aging on dynamic AV nodal field potential recording during atrial fibrillation (AF) in rabbit. Methods: Two groups of male New Zealand rabbits (neonatal 2-week-olds and adult...
Atrial Fibrillation (AF) is the most common cardiac arrhythmia. It naturally tends to become a chronic condition, and chronic Atrial Fibrillation leads to an increase in the risk of death. The study of the electrocardiographic signal, and in particular of the tachogram series, is a usual and effective way to investigate the presence of Atrial Fibrillation and to detect when a single event start...
introduction: atrial fibrillation (af) is the most prevalent cardiac arrhythmias that cardiologists and internists encounter. the goal of this article is to clarify an overview of the evidence linking inflammation to af existence, which may highlight the effect of some pharmacological agents that have genuine potential to reduce the clinical burden of af by modulating inflammatory pathways. mat...
Atrial fibrillation (AF) is the most common sustained atrial arrhythmia conferring a higher morbidity and mortality. Despite the increasing incidence of AF; available therapies are far from perfect. Dietary fish oils, containing omega 3 fatty acids, also called polyunsaturated fatty acid [PUFA] have demonstrated beneficial electrophysiological, autonomic and anti-inflammatory effects on both at...
BACKGROUND To predict the recurrence of atrial fibrillation is important for selecting patients who will be undergoing catheter ablation, several studies respectively evaluated the risk factor of the recurrence of atrial fibrillation post-ablation. OBJECTIVE To investigate the factors predicting the recurrence of atrial fibrillation (AF) after catheter ablation. METHODS 186 patients (55.12 ...
There are exciting new developments in several areas of atrial fibrillation (AF) management that carry the hope of improving outcomes in AF patients. This paper is an executive summary that summarises the proceedings from the 3rd AFNET/EHRA consensus conference on atrial fibrillation, held in Sophia Antipolis from November 7th to 9th 2010, shortly after the release of the new ESC guidelines on ...
