315,000 with atrial flutter (2019) [10] Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [11][12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4]
Cardiology. Atrioventricular reentrant tachycardia (AVRT), or atrioventricular reciprocating tachycardia, is a type of heart arrhythmia with an abnormally fast rhythm (tachychardia); it is classified as a type of supraventricular tachycardia (SVT). AVRT is most commonly associated with Wolff–Parkinson–White syndrome, but is also seen in ...
Cardiology, electrophysiology. Atrial tachycardia is a type of heart rhythm problem in which the heart 's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers (atria) of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.
1. 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. The maximum CHADS 2 score is 6, whilst the ...
antiarrythmic agents, diuretics, catheter ablation, pacemaker [1] 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. [1][5] People with TIC may have symptoms ...
The management of atrial fibrillation (AF) is focused on preventing temporary circulatory instability, stroke and other ischemic events. Control of heart rate and rhythm are principally used to achieve the former, while anticoagulation may be employed to decrease the risk of stroke. [ 1] Within the context of stroke, the discipline may be ...
Ashman phenomenon, also known as Ashman beats, describes a particular type of wide QRS complex, often seen isolated that is typically seen in atrial fibrillation. It is a type of cardiac aberrancy and it is more often misinterpreted as a premature ventricular complex. It is named for Richard Ashman (of New Orleans) (1890 –1969), [1] after ...
Atrial fibrillation and atrial flutter resulted in 112,000 deaths in 2013, up from 29,000 in 1990. [10] However, in most recent cases concerning the SARS-CoV‑2 pandemic, cardiac arrhythmias are commonly developed and associated with high morbidity and mortality among patients hospitalized with the COVID-19 infection, due to the infection's ...
