On an ecg strip multiple electrical events called p q r s t and u may be observed.
Mat ecg rhythm.
If the p wave has a morphology different from the typical sinus morphology it is termed ectopic meaning.
Most commonly seen in patients with severe copd or congestive heart failure.
Multifocal atrial tachycardia mat overview a rapid irregular atrial rhythm arising from multiple ectopic foci within the atria.
It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation.
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.
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.
Accelerated junctional rhythm ecg example 1 accelerated junctional rhythm ecg example 2 atrial bigeminy ecg.
Arrhythmia is an abnormally slow or fast heart rate or an irregular cardiac rhythm.
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.
Multifocal atrial tachycardia mat is a cardiac arrhythmia caused by multiple sites of competing atrial activity.
It s one of many types of heart arrhythmias or irregular heart rhythms.

Ecg rhythms are used to evaluate normal or abnormal cardiac conditions.
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.
