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]
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.
Thus, the CHA 2 DS 2-VASc score is a refinement of CHADS 2 [8] [10] score and extends the latter by including additional common stroke risk factors, that is, age 65–74, female gender and vascular disease. [11] In the CHA 2 DS 2-VASc score, 'age 75 and above' also has extra weight, with 2 points.
Mixed evidence exist on the comparison between GARFIELD-AF bleeding score over the HAS-BLED. [ 5 ] [ 6 ] 2020 ESC guidelines on atrial fibrillation recommend assessment of bleeding risk in AF using the HAS-BLED bleeding risk schema as a simple, easy calculation, [ 7 ] whereby a score of ≥3 indicates "high risk" and some caution and regular ...
Atrial fibrillation: Red dots show atrial fibrillation activity. Atrial fibrillation meets the definition of SVT when associated with a ventricular response greater than 100 beats per minute. It is characterized as an "irregularly, irregular rhythm" both in its atrial and ventricular depolarizations and is distinguished by its fibrillatory ...
Fibrillation can affect the atrium (atrial fibrillation) or the ventricle (ventricular fibrillation): ventricular fibrillation is imminently life-threatening. Atrial fibrillation affects the upper chambers of the heart, known as the atria. Atrial fibrillation may be due to serious underlying medical conditions and should be evaluated by a ...
Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure.
In Europe and North America, as of 2014, atrial fibrillation affects about 2% to 3% of the population. [51] Atrial fibrillation and atrial flutter resulted in 112,000 deaths in 2013, up from 29,000 in 1990. [27] Sudden cardiac death is the cause of about half of deaths due to cardiovascular disease or about 15% of all deaths globally. [52]
