Multifocal atrial tachycardia. “Multifocal” means having more than one focus and “atrial” refers to the heart’s two upper chambers, called atria. In this type of tachycardia, those irregular signals come from three or more places in the heart’s upper chambers. 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. Multifocal atrial tachycardia (MAT) is a supraventricular tachycardia with a rapid, irregular atrial rhythm arising from multiple ectopic foci within the atria. 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 beatmungspflichtig. Table of Content … Betroffene Säuglinge sind wegen eines linksventrikulären Pumpversagens oft schwer krank und ggf. This arrhythmia is characterized by a heart rate of greater than 100 beats per minute with organized atrial activity yielding three or more different non-sinus P-wave morphologies in the same lead. Multifocal atrial tachycardia (MAT) is an arrhythmia that can be seen in a variety of clinical disorders [ 1 ]. Card Electrophysiol Rev. Supraventrikuläre Tachykardie. The mechanism of the arrhythmia may be delayed afterdepolarizations leading to triggered activity, but this has not been firmly established. Atrial tachycardiais a type of heart rhythm problemin which the heart's electrical impulse comes from an ectopic pacemaker(that is, an abnormally located cardiac pacemaker) in the upper chambers (atria) of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity. Multifocal Atrial Tachycardia. If you have MAT, your heart beats much faster than normal. Multifocal atrial tachycardia (MAT) is an abnormal heart rhythm, specifically the type of supraventricular tachycardia, which is very common in the elderly and is associated with the exacerbation of chronic obstructive pulmonary disease (COPD). Die Diagnose einer MAT basiert auf dem elektrokardiografischen Befund. In multifocal atrial tachycardia, several different foci activate the atria. Die Vorhoffrequenz ist variabel und liegt meist zwischen 100 und 300/min. Synonym(s): multifocal atrial tachycardia Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD). Rate: 150-250P waves: VisibleQRS: Narrow Atrial Tachycardia is caused by an irritated site in the Atria. Aufgrund einer variablen AV-Überleitung kommt es zu Blockierungen aller Grade sowie zu intraventrikulären Reizleitungsverzögerungen mit variabel deformierten QRS-Komplexen ("chaotisches" EKG-Bild). Since improvement in … Eine isoelektrische Linie ist durchgehend erkennbar. Treatment of the multifocal atrial tachycardia (MAT) Treat the underlying cause. Multifocal atrial tachycardia (MAT) is a type of irregular heartbeat in which the heart beats faster than it should. Multifocal atrial tachycardia (MAT) is an arrhythmia that can be seen in a variety of clinical disorders [ 1 ]. Part of the reason it’s poorly understood is that MAT isn’t a very common type of arrhythmia. The nonelectrophysi-ologist must be prepared for acute man … Fifteen patients had echocardiograms as part of their evaluation; 11 demonstrated normal cardiac function and chamber dimensions. Verapamil is negatively inotropic and a vasodilator. MAT commonly develops in elderly people during periods of acute exacerbation of underlying pulmonary disease.' L), 80 percent ofpatients had ventricular premature beats (VPBs), 44 percent had paired VPBs, and 25 percent had ventricular runs. Atrial activity is well organized, with at least three morphologically distinct P waves, irregular P-P intervals, and an isoelectric baseline between the P waves. Die multifokale atriale Tachykardie, kurz MAT, ist eine supraventrikuläre Tachyarrhythmie und eine Sonderform der fokalen atrialen Tachykardie. Atrial tachycardia is the least common type of supraventricular tachycardia. Ca++ channel blockers (verapamil.) multifocal atrial tachycardia: multifocal origin of tachycardia within the atrium; often confused with atrial fibrillation during physical examination. Without an EKG, it’d be hard to tell the difference between MAT and some other type of arrhythmia. Sehr selten ist sie Teil eines Syndroms (z.B. 1997; 1 (1/2): p.71-75. Introduction MULTIFOCAL atrial tachycardia (MAT) is defined as an atrial rate greater than 100 beats per min with more than 50% of the atrial depolarisations being ectopic, and at least three different P-wave morphologies with varying PR and PP intervals.' © 2005 - 2019 WebMD LLC. Verapamil is negatively inotropic and a vasodilator. Sometimes people with MAT have these signs: But many times, people with MAT don’t feel like their heart isn’t beating normally or notice other signs. EKG, This happens because the signals that control your heartbeat aren’t working right. It’s hard to tell from a physical exam if a person has MAT. Unter Beachtung der Nebenwirkungen und Kontraindikationen werden zur symptomatischen Therapie Magnesium, Digitalis, Amiodaron, Propafenon, Verapamil, Diltiazem und/oder Betablocker eingesetzt. Your doctor may recommend other treatments, such as beta-blockers or calcium channel blockers, depending on what other conditions you have. It's generally seen in children with underlying heart disorders such as congenital heart disease, particularly those who've had heart surgery. The mechanism of the arrhythmia may be delayed afterdepolarizations leading to triggered activity, but this has not been firmly established. Multifocal atrial tachycardia (MAT) is an automatic arrhythmia characterized by an atrial rate greater than 100 beats/minute with organized, discrete, nonsinus P waves of at least three different forms in the same lead on the ECG. The percent por- tion representative of MAT was 67.7% and the remainder (33.3%) was MAR. Bei älteren Patienten besteht häufig eine Assoziation mit pulmonalen Erkrankungen, die zu einer Vorhofbelastung führen: Die MAT basiert vermutlich auf getriggerten Spätpotenzialen (Automatie) in mindestens drei unterschiedlichen ektopen Reizbildungszentren im rechten und/oder linken Vorhof. As with any other form of tachycardia, the underlying mechanism can be either the rapid discharge of an abnormal focus, the presence of a ring of cardiac tissue that gives rise to a circle movement, or a triggered rapid rhythm due to other patholo People with MAT often need treatment in the hospital or intensive care unit (ICU). The anatomic origin of focal atrial tachycardias is not an accurate predictor of the mechanism.3 Focal atrial tachycar-dias arise along the crista terminalis, in the right and left atrial appendages, within the coronary sinus, in the … 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). Fallot-Tetralogie) oder nach kürzlich erfolgter Herzoperation auftreten. MAT is usually associated with severe … A rapid, irregular atrial rhythm arising from multiple ectopic foci within... Electrocardiographic Features. Keep in mind that this is because of the other health problems people with MAT tend to have, not the abnormal heart rhythm itself. multifocal atrial tachycardia is often related to underlying illnesses, frequently occurring in patients experiencing an exacerbation of chronic obstructive pulmonary disease (COPD) 6), a pulmonary thromboembolism, an exacerbation of heart failure, or severe illness, especially under critical care with inotropic infusion. Atrial activity is well organized, with at least 3 morphologically distinct P waves, irregular P-P intervals, and an isoelectric baseline between the P waves. multifocal tachycardia are limited. [Article in German] Toussaint R, Hofstetter R, von Bernuth G. Four infants with multifocal atrial tachycardia are presented. This happens when the upper chambers of your heart send too many electrical signals to … (Electrolytes include sodium, potassium, calcium, and magnesium.) Non-drug ways you can manage your condition.

Eine MAT ist sehr selten und kann prinzipiell in jedem Lebensalter auftreten. Tachycardia can be categorized into two main types, namely supraventrikular or ventricular, where previously divided into narrow complex tachycardia and a wide complex tachycardia. and multifocal atrial tachycardia, each of which may be transient, requiring no chronic therapy. Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD). When your heart beats normally, there are between 60 and 100 beats per minute. It’s one of many types of heart arrhythmias or irregular heart rhythms. Die multifokale atriale Tachykardie, kurz MAT, ist eine supraventrikuläre Tachyarrhythmie und eine Sonderform der fokalen atrialen Tachykardie. Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity. What is multifocal atrial tachycardia? Atrial tachycardia (AT) is a regular atrial rhythm at a constant rate of >100 beats per minute originating outside of the sinus node (waveform 1) [ 1 ]. In most cases, the best way to treat MAT is to treat the other health problems.

Of these 11, 3 had normal ventricular function and cardiopulmonary symptoms, 4 patients had abnormal function but no symptoms, and 4 had normal function and no symptoms. Zur Abklärung der Ursache können laborchemische Untersuchungen und eine Echokardiographie sinnvoll sein. It also can happen in people who have an imbalance of electrolytes, such as magnesium or potassium. Der Ort der abnormen Erregungsbildung im Vorhof lässt sich anhand der Konfiguration der P-Welle ermitteln: Die Therapie einer MAT basiert auf der Behandlung der zugrundeliegenden Erkrankung und Korrektur evtl. 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.
