Most commonly seen in patients with severe copd or congestive heart failure.
Mat cardiac arrhythmia.
Atrial activity is well organized with at least 3 morphologically distinct p waves irregular p p intervals and an isoelectric baseline.
It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation.
This node is considered the heart s natural pacemaker it helps control the heartbeat.
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.
Multifocal atrial tachycardia may occur in children.
Study of a patient s cardiac rhythms using an ekg may indicate normal or abnormal conditions.
Multifocal atrial tachycardia mat is a cardiac arrhythmia caused by multiple sites of competing atrial activity.
Multifocal atrial tachycardia may be intermittent with intervening periods of sinus rhythm.
It is characterized by an irregular atrial rate greater than 100 beats per minute bpm.
In mat many locations in the atria fire signals at the same time.
When the heart detects a signal it contracts or beats.
Paroxysmal means that the episode of arrhythmia begins and ends abruptly.
A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria.
Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node.
Abnormal rhythms are called arrhythmia or sometimes dysrhythmia.
The normal heart rate in adults is about 60 to 100 beats per minute.
The normal heart rate is faster in children.
It s one of many types of heart arrhythmias or irregular heart rhythms.
Multifocal atrial tachycardia mat overview.
Multifocal atrial tachycardia mat is a type of irregular heartbeat in which the heart beats faster than it should.
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.
