Mat Cardiac Arrhythmia

This node is considered the heart s natural pacemaker it helps control the heartbeat.

Mat cardiac arrhythmia.

Most commonly seen in patients with severe copd or congestive heart failure. Paroxysmal means that the episode of arrhythmia begins and ends abruptly. When the heart detects a signal it contracts or beats. Multifocal atrial tachycardia mat overview.

Multifocal atrial tachycardia mat is a cardiac arrhythmia caused by multiple sites of competing atrial activity. Study of a patient s cardiac rhythms using an ekg may indicate normal or abnormal conditions. 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. A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria.

Paroxysmal atrial tachycardia is a type of arrhythmia or irregular heartbeat. Atrial means that arrhythmia starts in the. Multifocal atrial tachycardia mat is a type of irregular heartbeat in which the heart beats faster than it should. In mat many locations in the atria fire signals at the same time.

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

Atrial activity is well organized with at least 3 morphologically distinct p waves irregular p p intervals and an isoelectric baseline. The normal heart rate is faster in children. Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node. It is characterized by an irregular atrial rate greater than 100 beats per minute bpm.

It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation.
