The laboratory test, C-Reactive Protein (CRP), has become well established as a marker of inflammation. Recently a high CRP level (indicating an increase in inflammation) was identified as a risk factor for atrial fibrillation. We are conducting this study with patients such as yourself with atrial fibrillation who are planning to undergo cardioversion to determine what sort of relationship exists between CRP levels and atrial fibrillation. We will then look at success rates of converting atrial fibrillation to normal sinus rhythm, compared to patients' CRP levels.

The purpose of this study is to investigate whether fish oil supplements may be beneficial in preventing the recurrence of atrial fibrillation after cardioversion. Atrial fibrillation is ...
The Biorhythm study aims to investigate the utility of new biomarkers (e.g. MR proANP, ST2) measured pre-procedure for the prediction of procedural success in patients with atrial fibrilla...
To investigate if in acute symptomatic atrial fibrillation (AF) the early (>2 hrs but within 12 hrs of the beginning of the arrhythmia) electrical cardioversion leads to a longer recurrenc...
We aim to investigate the immediate success rate (rate of termination of atrial fibrillation) of dual shock cardioversion compared with standard single shock cardioversion in patients with...
A symptomatic episode of the heart rhythm disorder 'atrial fibrillation' (AF) is a frequent reason for visits to the emergency department. Currently, in the majority of cases, immediate (e...
It is unknown whether cardioversion of atrial fibrillation causes thromboembolic events or is a risk marker. To assess causality, we examined the temporal pattern of thromboembolism in patients having...
Atrial fibrillation is one of the most common arrhythmias. As the symptoms can be abrupt in onset it is associated with a substantial burden on the medical emergency system. By routine practice patien...
Atrial fibrillation induces reversible electrical and mechanical modifications (atrial remodeling). Atrial stunning is a mechanical dysfunction with preserved bioelectrical function, occurring after s...
Atrial fibrillation is the most common sustained arrhythmia encountered in primary care practice and represents a significant burden on the health care system with a higher than expected hospitalizati...
Atrial fibrillation is the most frequent sustained arrhythmia. Atrial fibrillation often recurs after restoration of normal sinus rhythm. Antiarrhythmic drugs have been widely used to prevent recurren...
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 condition caused by dysfunctions related to the SINOATRIAL NODE including impulse generation (CARDIAC SINUS ARREST) and impulse conduction (SINOATRIAL EXIT BLOCK). It is characterized by persistent BRADYCARDIA, chronic ATRIAL FIBRILLATION, and failure to resume sinus rhythm following CARDIOVERSION. This syndrome can be congenital or acquired, particularly after surgical correction for heart defects.
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.
