One-third of stroke and transient ischemic attack (TIA) are cryptogenic, and paroxysmal atrial fibrillation (PAF) has been suggested as a possible cause for these cryptogenic strokes. Multiple studies have recently evaluated long-term cardiac rhythm monitoring with good yield for PAF. The duration of monitoring varies between studies as well as the qualifying event definition. Moreover, the cli...

Atrial fibrillation is the commonest clinical arrhythmia, is increasing in incidence and prevalence, and is associated with substantial morbidity and mortality. The arrhythmia may be paroxysmal (self-limiting), persistent (amenable to cardioversion), or permanent. Especially in its paroxysmal form, atrial fibrillation may be initiated by rapidly firing foci, generally located in the proximal pu...

A case is reported of recurrence of paroxysmal atrial fibrillation after pulmonary vein ablation. A second procedure achieved isolation of three pulmonary veins and showed persistence of pulmonary vein tachycardia in one with implications concerning the electrophysiology of atrial fibrillation.

The case of an 18-year-old woman with recurrent idiopathic catecholamine-sensitive paroxysmal atrial fibrillation is reported. Recordings of multiple initiations of atrial fibrillation at the proximal part of the right superior pulmonary vein suggested local reentry in the vein as the mechanism of atrial fibrillation. A single radiofrequency pulse delivered at this site resulted in definite cur...

The purpose of this article is to discuss the relationship between sympathovagal dysfunction and the occurrence of paroxysmal atrial fibrillation. Onset of atrial fibrillation is subject to circadian variation; shorter episodes occur more frequently during the day, whereas longer episodes occur less frequently at night. Vagally mediated atrial fibrillation typically is preceded by bradycardia, ...

Use of cigarettes and smokeless tobacco is a considerable public health problem. In Turkey, a type of smokeless tobacco called Maras powder (MP) is widely used in the Southeastern region. We present a case of paroxysmal atrial fibrillation that was suspected to be caused by the use of MP, which has never previously been noted in the literature. A 46-year-old man was admitted to our emergency de...

Atrial fibrillation is the most common sustained cardiac arrhythmia and associated with significant morbidity mortality. Coronary artery disease frequently coexists AF, management of these conditions can be challenging. Endurance veteran athletes are a population at high risk to have episodes paroxysmal atrial fibrillation. Herewith author describes an original case induced myocardial ischemia ...

BACKGROUND From a therapeutic viewpoint, it is important to differentiate the underlying causes of embolism in patients with cryptogenic stroke, such as aortic arch atheroma, patent foramen ovale, and paroxysmal atrial fibrillation. We investigated the clinical and radiological characteristics of these 3 common causes of cryptogenic embolism to develop models for decision making in etiologic wo...
