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 ...

Sarcoidosis is a systemic granulomatous disease that affects the myocardium. Although ventricular arrhythmias are well known manifestations of cardiac involvement, there is increasing evidence that a significant proportion of patients with cardiac sarcoidosis (CS) also have atrial arrhythmias, atrial fibrillation being the most frequent. The incidence and mechanism of atrial fibrillation in CS ...

Objective: To assess long term mortality and identify factors associated with the development of permanent atrial fibrillation after atrioventricular (AV) node ablation for drug refractory paroxysmal atrial fibrillation. Design: Retrospective cohort study. Setting: UK tertiary centre teaching hospital. Patients: Patients admitted to the University Hospital Birmingham between January 1995 and De...

OBJECTIVES This study sought to examine the long-term outcomes of patients hospitalized with heart failure and atrial fibrillation. BACKGROUND Atrial fibrillation is common among patients hospitalized with heart failure. Associations of pre-existing and new-onset atrial fibrillation with long-term outcomes are unclear. METHODS We analyzed 27,829 heart failure admissions between 2006 and 200...

BACKGROUND Probability of survival from sudden cardiac arrest caused by ventricular fibrillation (VF) decreases rapidly with fibrillation duration. We hypothesized that cellular ischemia/fibrillation-induced electrophysiological deterioration underlies decreased survival. METHODS AND RESULTS We determined fibrillation monophasic action potential (MAP) morphology including action potential fre...
