Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD). Normally, the heart rate is controlled by a cluster of cells called the ...
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 .
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]
Ashman phenomenon. 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 ...
Medications, medical procedures, surgery [5] Frequency. ~3% [6] [7] [8] Supraventricular tachycardia ( SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [2] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia, which start within the lower chambers of the heart. [2]
Atrial flutter ( AFL) is a common abnormal heart rhythm that starts in the atrial chambers of the heart. [1] When it first occurs, it is usually associated with a fast heart rate and is classified as a type of supraventricular tachycardia. [2] Atrial flutter is characterized by a sudden-onset (usually) regular abnormal heart rhythm on an ...
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 ...
Tachycardia-induced cardiomyopathy. 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 associated with heart failure (e.g ...
