INTRODUCTION Atrial fibrillation and atrial flutter account for one third of hospitalizations due to arrhythmias, determining great social and economic impacts. In Brazil, data on hospital care of these patients is scarce. OBJECTIVE To investigate the arrhythmia subtype of atrial fibrillation and flutter patients in the emergency setting and compare the clinical profile, thromboembolic risk a...

AIM We aimed to investigate whether different measures of obesity could similarly predict atrial fibrillation, and whether the atrial fibrillation risk associated with obesity is dependent on presence of metabolic syndrome. MATERIAL AND METHODS We performed our study in a population-based longitudinal cardiovascular study, comprising 1 924 men and 2 097 women, aged 60 years, from Stockholm. B...

Background. The goal of the report was to study the long-term incidence and the independent predictors for chronic atrial fibrillation and stroke in 507 paced patients with sick sinus syndrome, adjusting for differences in baseline clinical variables with multivariate analysis. Methods and Results. From 1980 to 1989, we implanted 376 dual-chamber, 19 atrial, and 112 ventricular pacemakers to tr...

• The mechanisms of atrial fibrillation and flutter have been subjects of continuous controversy. Fibrillation is a more complicated arrhythmia than flutter, and many previous analyses of flutter have been extended to fibrillation. Since the similarity of the mechanisms underlying these two arrhythmias has not been demonstrated, many current theories on the mechanism of fibrillation are therefo...

OBJECTIVE To test the hypothesis that including preoperative electrocardiogram (ECG) characteristics with clinical variables significantly improves the new-onset postoperative atrial fibrillation prediction model. DESIGN Retrospective analysis. SETTING Single-center university hospital. PARTICIPANTS Five hundred twenty-six patients, ≥ 18 years of age, who underwent coronary artery bypass ...

BACKGROUND The development of new-onset atrial fibrillation in sepsis has been associated with adverse outcomes. METHODS A systematic literature search was conducted to retrieve articles that investigated the association of new-onset atrial fibrillation in patients diagnosed with sepsis. The primary outcome of interest was the pooled risk ratio (RR) of in-hospital mortality in patients with n...

INTRODUCTION AND OBJECTIVE Atrial fibrillation is the most common arrhythmia seen in clinical practice. The objective of this study was to know the frequency of atrial fibrillation and the characteristics of patients with atrial fibrillation in the Cardiotens study. MATERIAL AND METHOD A cross-section study with systematic selection of the study sample. All 32,051 outpatients seen on the same...

Persistent atrial fibrillation is one of the most common arrhythmias, which is caused by disorderly excited and invalid contract room sex rhythm in patients with arrhythmia. Evidences have indicated that plasma concentration levels of bilirubin and serum uric acid are associated with progression of auricular fibrillation. In this clinical investigation, regression analysis between auricular fib...

AIMS Idiopathic atrial fibrillation describes atrial fibrillation of unknown origin occurring without heart disease. Mortality is considered unaffected by idiopathic atrial fibrillation. We used the long follow-up period (23 years on average) of the Paris Prospective Study I to assess the mortality of idiopathic atrial fibrillation subjects in middle-aged men. METHODS 7746 working Frenchmen, ...

The management of atrial fibrillation involves control of the ventricular response rate, anticoagulation to reduce the risk of stroke and attempts to maintain sinus rhythm. The approach to patients with atrial fibrillation has become increasingly complex as therapeutic options have expanded. The ultimate reasons to treat atrial fibrillation include improvement in symptoms, reduction in adverse ...
