Different studies with real-life data and randomized controlled trials have shown a detection rate of paroxysmal atrial fibrillation (AF) of 10-20% in patients with cryptogenic stroke using insertable continuous cardiac monitoring for 6 months. More studies are needed, however, to identify factors which can be used to select the patients where the possibility of detecting AF with prolonged rhythm monitoring is highest, to evaluate the best duration of rhythm monitoring, to determine the optimal deﬁnition of short-term AF that warrants intervention and to evaluate whether intervention results in improved clinical outcomes.
Methods: The NOR-FIB study is a multi-centre prospective observational trial, designed to evaluate detection of AF in cryptogenic stroke and transient ischemic attack (TIA). Patients admitted with cryptogenic stroke or TIA in stroke units in the Nordic countries, aged 18-80 years are included and have the Reveal LINQ® Insertable cardiac monitor system implanted for 12 months for the purpose of AF detection. Biomarkers that may identify patients, who could derive the most clinical benefit from the detection of AF by prolonged monitoring, are being studied.
Conclusion: This NOR-FIB study will increase our knowledge regarding the occurrence of AF in patients with cryptogenic stroke and TIA that potentially can improve secondary prevention. The study will provide information on biomarkers that may be used to select cryptogenic TIA and stroke patients for long-term monitoring as well as information on the significance of short-term AF and optimal duration of cardiac rhythm monitoring.

Various properties of digoxin have been exploited for decades, amongst which are its positive inotropy used in the treatment of heart failure, and its vagotonic effect used to slow ventricular respons...
Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.
A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)
A THROMBIN inhibitor which acts by binding and blocking thrombogenic activity and the prevention of thrombus formation. It is used to reduce the risk of stroke and systemic EMBOLISM in patients with nonvalvular atrial fibrillation.
A morpholine and thiophene derivative that functions as a FACTOR XA INHIBITOR and is used in the treatment and prevention of DEEP-VEIN THROMBOSIS and PULMONARY EMBOLISM. It is also used for the prevention of STROKE and systemic embolization in patients with non-valvular ATRIAL FIBRILLATION, and for the prevention of atherothrombotic events in patients after an ACUTE CORONARY SYNDROME.

Stroke - Cerebrovascular Disease (CVA)
A stroke is a serious medical condition that occurs when the blood supply to part of the brain is cut off. Strokes are a medical emergency and prompt treatment is essential because the sooner a person receives treatment for a stroke, the less damage is ...
