Mat Cardiac Arrhythmia

When the heart detects a signal it contracts or beats.

Mat cardiac arrhythmia.

Multifocal atrial tachycardia may occur in children. Most commonly seen in patients with severe copd or congestive heart failure. A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria. Atrial activity is well organized with at least 3 morphologically distinct p waves irregular p p intervals and an isoelectric baseline.

Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node. In mat many locations in the atria fire signals at the same time. 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. The normal heart rate is faster in children.

Study of a patient s cardiac rhythms using an ekg may indicate normal or abnormal conditions. Paroxysmal atrial tachycardia is a type of arrhythmia or irregular heartbeat. Multifocal atrial tachycardia may be intermittent with intervening periods of sinus rhythm. The normal heart rate in adults is about 60 to 100 beats per minute.

It s one of many types of heart arrhythmias or irregular heart rhythms. It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation. Multifocal atrial tachycardia mat overview. Multifocal atrial tachycardia mat is a type of irregular heartbeat in which the heart beats faster than it should.

Multifocal atrial tachycardia mat is a cardiac arrhythmia caused by multiple sites of competing atrial activity. Paroxysmal means that the episode of arrhythmia begins and ends abruptly. This node is considered the heart s natural pacemaker it helps control the heartbeat. Abnormal rhythms are called arrhythmia or sometimes dysrhythmia.

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.
