The aim of this study was to evaluate a spatial correlation between active atrial fibrillation (AF) drivers measured by ECGI and complex fractionated atrial electrograms (CFAEs) in patients with persistent AF.

Atrial fibrillation is a well-known risk factor for cardioembolic stroke; a number of risk stratification scoring systems have been developed to help differentiate which patients would stand to benefi...
Atrial fibrillation is one of the most common causes of ischaemic stroke, especially among the elderly. Cardiogenic stroke accounts for approximately 15-25& of all ischaemic strokes, depending on diff...
Deficiency of testosterone was associated with the susceptibility of atrial fibrillation. Angiotensin-II receptor antagonists were shown to reduce atrial fibrillation by improving atrial electrical re...
Radiofrequency ablation has become a safe and effective treatment for atrial fibrillation. We believe that referral to an electrophysiologist for consideration of ablation may allow for better rhythm ...
Atrial fibrillation (AF) wavefront dynamics are complex and difficult to interpret, contributing to uncertainty about the mechanisms that maintain AF. We aimed to investigate the interplay between rot...
The aim of this study is to evaluate whether performing complex fractionated atrial electrograms ablation improves outcomes in persistent or atrial fibrillation ablation.
The purpose of this study is to characterise which fractionated electrogram morphologies are important to target in the catheter ablation of atrial fibrillation.
The end point of catheter ablation at complex fractionated atrial electrograms (CFAE) was not established yet. Furthermore, incomplete CFAE ablation may have a potential to develop atrial ...
Comparison of Effectiveness of Ranolazine Plus Metoprolol Combination vs. FlecainidE pluS Metoprolol Combination in ATrial Fibrillation Recurrences FOllowing PhaRmacological or Electrical CardioverSion of AtRial Fibrillation
Atrial fibrillation (AF) is the most common arrhythmia in clinical practice with a prevalence reaching 5% in patients older than 65 years and an incidence that increases progressively with...
This is a sigle-center, prospective study to evaluate the role of D-Dimer testing in patients with atrial fibrillation receiving Dabigatran or warfarin anticoagulation therapy.
Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.
A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)
Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.
A THROMBIN inhibitor which acts by binding and blocking thrombogenic activity and the prevention of thrombus formation. It is used to reduce the risk of stroke and systemic EMBOLISM in patients with nonvalvular atrial fibrillation.
