It’s more common in men and in people with one or more other health problems. Adenosin oder eine elektrische Kardioversion sind i.d.R. Multifocal atrial tachycardia. Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity. That’s where MAT gets its name. 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).

Of these 11, 3 had normal ventricular function and cardiopulmonary symptoms, 4 patients had abnormal function but no symptoms, and 4 had normal function and no symptoms. The mechanism of the arrhythmia may be delayed afterdepolarizations leading to triggered activity, but this has not been firmly established. Atrial tachycardiais a type of heart rhythm problemin 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. Multifocal atrial tachycardia (MAT) is a supraventricular tachycardia with a rapid, irregular atrial rhythm arising from multiple ectopic foci within the atria.

Tachycardia can be categorized into two main types, namely supraventrikular or ventricular, where previously divided into narrow complex tachycardia and a wide complex tachycardia. L), 80 percent ofpatients had ventricular premature beats (VPBs), 44 percent had paired VPBs, and 25 percent had ventricular runs. Anytime the heart beats faster than 100 beats per minute, it’s called a tachycardia (pronounced tak-ih-KAHR-dee-uh). It's generally seen in children with underlying heart disorders such as congenital heart disease, particularly those who've had heart surgery.
