It s one of many types of heart arrhythmias or irregular heart rhythms.
Mat ecg rhythm.
Multifocal atrial tachycardia mat is a cardiac arrhythmia caused by multiple sites of competing atrial activity.

The ecg in ectopic atrial rhythm and atrial tachycardia a regular rhythm with p waves that differ in terms of contour appearance from the sinus p waves.
If the p waves in lead ii are retrograde negative the diagnosis is simple because sinus p waves can never be negative in lead ii.
The first ecg strip below shows a p wave with sinus morphology thus normal sinus rhythm.
Multifocal atrial tachycardia mat overview a rapid irregular atrial rhythm arising from multiple ectopic foci within the atria.
It is characterized by an irregular atrial rate greater than 100 beats per minute.
It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation.
Arrhythmia is an abnormally slow or fast heart rate or an irregular cardiac rhythm.

On an ecg strip multiple electrical events called p q r s t and u may be observed.
Most commonly seen in patients with severe copd or congestive heart failure.
Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node.
If the p wave has a morphology different from the typical sinus morphology it is termed ectopic meaning.
