Multifocal atrial tachycardia (MAT) is a rapid heart rate.It occurs when too many signals (electrical impulses) are sent from the upper heart (atria) to the lower heart (ventricles). Once those are more controlled, the heart irregularity will likely get better. 92 There is debate regarding whether there needs to be two or three distinct P waves in addition to the sinus P wave.93, 94 MAT most commonly occurs … Multifocal Atrial Tachycardia.

Conditions such as hy-poxemia, electrolyte imbalance, catechol-amine excess (endogenous and exoge-nous), and other metabolic disturbances predispose patients (with and without preexisting arrhythmic substrates) to tachyarrhythmias. People taking certain medications used to treat heart or lung problems may be more likely to have MAT. Multifocal atrial tachycardia (MAT) is a cardiac arrhythmia caused by multiple sites of competing atrial activity. The initial treatment of multifocal atrial tachycardia should include supportive measures and aggressive reversal of precipitating causes. Heart Rate: >100 BPM Rhythm: Irregular Pacemaker site: ectopic sites in atria P waves: organized, discrete non-­‐sinus w/ atleast three different morphologies PRI: Varies Corresponding Author.

Multifocal atrial tachycardia (MAT) is a supraventricular tachycardia with a rapid, irregular atrial rhythm arising from multiple ectopic foci within the atria. Anytime the heart beats faster than 100 beats per minute, it’s called a tachycardia (pronounced tak-ih-KAHR-dee-uh). Bei Neugeborenen ist sie am häufigsten vorzufinden. In addition to a heart rate greater than 100 beats per minute, the characteristic electrocardiographic feature is variability in P wave morphology, with each unique P wave morphology felt to indicate a different site of atrial origin. Im Säuglingsalter findet sich bei der Mehrzahl der Patienten keine strukturelle Herzerkrankung, selten kann sie jedoch mit Herzfehlern (z.B.

A multifocal atrial mechanism-tachycardia or rhythm -was identified in 96 of 11,610 (0.8%) computerized ECGs and represented 14% of those computerized ECGs interpreted as atrial fibrillation (Table I). 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.
