As seen in figure 4 it is characterized by an irregular rhythm with clearly visible p waves on the contrary to atrial fibrillation but the p wave morphology varies from one beat to another.
Ectopic atrial afib mat.
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.

New data regarding verapamil and metoprolol.
Multifocal atrial tachycardia mat and rhythm discrete multifocal p waves occurring at rates of 100 250 min and with varying p r intervals should see at least 3 different p wave morphologies in a given lead.

Ectopic atrial rhythm is similar to ectopic atrial tachycardia but with hr 100 bpm.
Afib is an individual symptomatic experience.
I let it go 5 days before an ecg proved me wrong.
While ectopic atrial tachycardia eat has a single ectopic focus therefore a regular rhythm multiple atrial tachycardia mat has multiple foci conducting and therefore has an irregular rhythm.
Treating multifocal atrial tachycardia mat in a critical care unit.
What i thought was frequent ectopics i didn t feel afib symptomatic and it didn t feel irregular was infact afib.
It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation.
Post op was a very different story.
Most commonly seen in patients with severe copd or congestive heart failure.
Treatment of multifocal atrial tachycardia with verapamil.
Pre op i could separate quite easily from afib flutter ectopics.
