The European Heart Rhythm Association score of atrial fibrillation (or EHRA score) is a classification system for the extent of atrial fibrillation.It places patients in one of four categories based on how much they are limited during physical activity; the limitations/symptoms are in regard to normal breathing and varying degrees in shortness of breath and/or angina.
risk of stroke (for non-rheumatic atrial fibrillation) The CHADS 2 score and its updated version, the CHA 2 DS 2 -VASc score , are clinical prediction rules for estimating the risk of stroke in people with non-rheumatic atrial fibrillation (AF), a common and serious heart arrhythmia associated with thromboembolic stroke.
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia.

This technique is commonly used for solid tumors and has been applied with success in management of difficult to treat Ventricular Tachycardia and Atrial Fibrillation. [ 1 ] The most challenging cases involve palpitations that are secondary to supraventricular or ventricular ectopy or associated with normal sinus rhythm . [ 1 ]
Vernakalant, sold under the brand name Brinavess, is a class III antiarrhythmic drug for the acute conversion of atrial fibrillation, a kind of irregular heartbeat, in form of an intravenous infusion. It has been approved for use in the European Union and the United Kingdom since 2010.
