Mat Cardiac Arrhythmia

The most common underlying causes are heart failure atrial ischemia increased atrial pressure use of theophyllamine or chronic lung disease particularly chronic obstructive pulmonary disease.

Mat cardiac arrhythmia. Multifocal atrial tachycardia mat is a cardiac arrhythmia caused by multiple sites of competing atrial activity. Multifocal atrial tachycardia mat overview. Arrhythmia is an abnormally slow or fast heart rate or an irregular cardiac rhythm. It is characterized by an irregular atrial rate greater than 100 beats per minute bpm.

The normal heart rate is faster in children. Multifocal atrial tachycardia mat is a type of irregular heartbeat in which the heart beats faster than it should. Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node. Most commonly seen in patients with severe copd or congestive heart failure.

It s one of many types of heart arrhythmias or irregular heart rhythms. In mat many locations in the atria fire signals at the same time. Abnormal rhythms are called arrhythmia or sometimes dysrhythmia. This node is considered the heart s natural pacemaker it helps control the heartbeat.

Multifocal atrial tachycardia may occur in children. Multifocal atrial tachycardia may be intermittent with intervening periods of sinus rhythm. Multifocal or multiform atrial tachycardia mat is an abnormal heart rhythm specifically a type of supraventricular tachycardia that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease copd. Atrial activity is well organized with at least 3 morphologically distinct p waves irregular p p intervals and an isoelectric baseline.

When the heart detects a signal it contracts or beats. The normal heart rate in adults is about 60 to 100 beats per minute. It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation. Atrial means that arrhythmia starts in the.

A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria.
