OBJECTIVE To assess the clinical characteristics of patients with atrial fibrillation in the primary care setting. METHODS This was a 2-phase, cross-sectional, multicenter study: phase A assessed the proportion of atrial fibrillation patients assisted in primary care over 5 days; phase B analyzed atrial fibrillation patients' clinical characteristics and management. RESULTS In phase A, 119 ...

A case of Wolff-Parkinson-White syndrome associated with ventricular fibrillation is presented. The control of recurrent ventricular fibrillation with large doses of digitalis and other antiarrhythmic drugs, including propranolol, lidocaine, procainamide, and quinidine, is discussed. As far as we can determine, this is the first human case in which the precise onset of ventricular fibrillation ...

T here has been a long-standing consensus1 that the risk of embolization in patients with atrial fibrillation and rheumatic heart disease, in particular, mitral stenosis, is sufficiently high to justify anticoagulant prophylaxis. However, there has been no consensus in regard to nonrheumatic atrial fibrillation. The recognition that nonrheumatic atrial fibrillation is common and associated with...

OBJECTIVE We sought to determine whether in the absence of clinical stroke, people with atrial fibrillation experience faster cognitive decline than people without atrial fibrillation. METHODS We conducted a longitudinal analysis in the Cardiovascular Health Study, a community-based study of 5,888 men and women aged 65 years and older, enrolled in 1989/1990 or 1992/1993. Participants did not ...

Sleep apnea has been recognized as a factor predisposing to atrial fibrillation recurrence and progression. The effect of other sleep-disturbing conditions on atrial fibrillation progression is not known. We sought to determine whether frequent periodic leg movement during sleep is a risk factor for progression of atrial fibrillation. In this retrospective study, patients with atrial fibrillati...

The effect of surgical ablation of ablation of atrioventricular accessory pathways on the incidence of atrial fibrillation in patients with Wolff-Parkinson-White syndrome was examined and the results of preoperative electrophysiologic testing were studied to determine factors predictive of outcome. Among 50 consecutive surgical cases, 19 patients were identified with a past history of at least ...

Primary ventricular fibrillation was seen in 20 of 450 consecutive patients (4-4%) admitted within 24 hours after the onset of acute myocardial infarction. Compared with patients without primary ventricular fibrillation they showed a lower mean age group and a higher incidence of anterior infarction. Warning ventricular arrhythmias preceded primary ventricular fibrillation in 58% of cases. Howe...

BACKGROUND Pulmonary embolism (PE) may trigger atrial fibrillation through increased right atrial pressure and subsequent atrial strain, but the degree of evidence is low. In this study, we wanted to investigate the impact of incident venous thromboembolism (VTE) on future risk of atrial fibrillation in a prospective population-based study. METHODS AND RESULTS The study included 29 974 subjec...

The atrial electrocardiogram was studied in eight patients who developed intermittent atrial fibrillation following myocardial infarction. Thirty-two episodes of onset of atrial fibrillation and 28 episodes of spontaneous cessation were observed. An atrial premature beat followed by atrial tachycardia of variable duration always preceded the onset of atrial fibrillation. Spontaneous cessation o...

ventricular fibrillation is the cause of the most sudden deaths. the recent findings have clearly proved the correlation between the slope of restitution curve with ventricular fibrillation. cellular automata is a powerful tool for simulating complex phenomena in a simple language. in this paper, a simple model is proposed for the simulation of the property of restitution in a single cardiac ce...
