A randomized trial has recently demonstrated non-inferiority of cryoballoon vs. radiofrequency (RF) catheter ablation in patients with drug-refractory paroxysmal atrial fibrillation (AF). ...
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...
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 study will select all recruited patients with paroxysmal atrial fibrillation will be randomly allocated to receive oral rosuvastatin 20mg/day or blank control from 7 days before ablati...
Atrial fibrillation is the most common heart arrhythmia afflicting approximately 1% of the Danish population. Medical antiarrhythmic treatment is only moderately effective and has the risk...
The most efficient first-time invasive treatment, for achieving sinus rhythm, in symptomatic paroxysmal atrial fibrillation has not been established. We aimed to compare percutaneous catheter and vide...
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...
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...
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 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 ...
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.
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.
