Mat Cardiac Arrhythmia

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.

Mat cardiac arrhythmia.

Atrial activity is well organized with at least 3 morphologically distinct p waves irregular p p intervals and an isoelectric baseline. Study of a patient s cardiac rhythms using an ekg may indicate normal or abnormal conditions. Abnormal rhythms are called arrhythmia or sometimes dysrhythmia. Paroxysmal means that the episode of arrhythmia begins and ends abruptly.

Multifocal atrial tachycardia mat is a type of irregular heartbeat in which the heart beats faster than it should. It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation. Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node. Atrial means that arrhythmia starts in the.

In mat many locations in the atria fire signals at the same time. A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria. The normal heart rate in adults is about 60 to 100 beats per minute. It is characterized by an irregular atrial rate greater than 100 beats per minute bpm.

Multifocal atrial tachycardia mat overview. The normal heart rate is faster in children. Paroxysmal atrial tachycardia is a type of arrhythmia or irregular heartbeat. When the heart detects a signal it contracts or beats.

Multifocal atrial tachycardia may occur in children. It s one of many types of heart arrhythmias or irregular heart rhythms. 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. Multifocal atrial tachycardia may be intermittent with intervening periods of sinus rhythm.

Most commonly seen in patients with severe copd or congestive heart failure.
