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 .
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 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 ...
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]
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]
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 ...
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 ...
Cardiology, electrophysiology. Premature atrial contraction ( PAC ), also known as atrial premature complexes ( APC) or atrial premature beats ( APB ), are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria. While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs ...
