BACKGROUND Ventricular fibrillation has deleterious metabolic and functional consequences for the heart. This study had two purposes: first, to define the effects of ventricular fibrillation during hypoxia on energy metabolism and accumulation of intracellular Na+ and, second, to test whether the occurrence of ventricular fibrillation can be predicted from functional or metabolic parameters. ...

The effect of surgical 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 one episode ...

BACKGROUND Atrial fibrillation is associated with increased risk of stroke and thromboembolism, possibly by conferring a prothrombotic or hypercoagulable state. However, it is unclear whether or not this differs in the clinical subgroups of chronic atrial fibrillation patients, that is, in those with paroxysmal, persistent or permanent atrial fibrillation. We therefore hypothesized that: (i) th...

Atrial fibrillation is the most common cardiac arrhythmia managed by emergency and acute general physicians. There is increasing evidence that selected patients with acute atrial fibrillation can be safely managed in the emergency department without the need for hospital admission. Meanwhile, there is significant variation in the current emergency management of acute atrial fibrillation. This r...

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 ...

The incidence of postoperative atrial fibrillation in cardiac surgery is still high despite major advances in anesthetic, pharmacological and surgical techniques. Its precise mechanism is still totally unknown. Postoperative atrial fibrillation increases length of stay as well as hospital costs. Rate of postoperative atrial fibrillation spontaneous conversion is high. Several protocols have bee...

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 ...

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...
