Using isochronous maps during radiofrequency ablation procedures may identify the driver zones responsible for atrial fibrillation maintenance with greater accuracy compared to a conventio...
A randomized trial has recently demonstrated non-inferiority of cryoballoon vs. radiofrequency (RF) catheter ablation in patients with drug-refractory paroxysmal atrial fibrillation (AF). ...
Atrial Fibrillation (AF) is a common heart rhythm problem that can be eliminated by a radiofrequency ablation procedure. The purpose of this study is to assess the amount of AF that occurs...
The study will assess the atrial fibrillation burden recorded By implantable loop recorder at 12 and 24 months compared to baseline. The patients with clinical indication fo catheter ablat...
The purpose of this study is to assess the value of ablation of high frequency sources following circumferential pulmonary veins isolation in patients with paroxysmal and persistent atrial...
Catheter ablation for rhythm control is recommended in specific patient populations with paroxysmal, persistent, or long-standing persistent atrial fibrillation. Pulmonary vein isolation is the corner...
Radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) is known to induce left atrial remodeling and prothrombotic response.
Radiofrequency catheter ablation of atrial fibrillation (AF) is one of the most complex ablation procedures. Both patients and operators are exposed to scattered radiation. This study evaluated the sa...
Left ventricular hypertrophy (LVH) is an independent predictor of new-onset atrial fibrillation. Whether LVH can predict the recurrence of arrhythmia after radiofrequency catheter ablation (RFCA) in p...
Compared with left atrial (LA) dimension, LA emptying fraction (LAEF) has received less emphasis as a predictor of atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA). In...
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)
The application, via IMPLANTED ELECTRODES, of short bursts of electrical energy in the radiofrequency range, interspersed with pauses in delivery of the current long enough to dissipate the generated heat and avoid heat-induced tissue necrosis.
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.
