Multifocal atrial tachycardia (MAT) is a supraventricular tachycardia with a rapid, irregular atrial rhythm arising from multiple ectopic foci within the atria. Normally, the heart rate is controlled by a cluster of cells called the sinoatrial node (SA node). What is multifocal atrial tachycardia? Treatment of the multifocal atrial tachycardia (MAT) Treat the underlying cause. Multifocal Atrial Tachycardia. MAT is usually associated with severe pulmonary disease and often accompanies critical illness. Aufgrund einer variablen AV-Überleitung kommt es zu Blockierungen aller Grade sowie zu intraventrikulären Reizleitungsverzögerungen mit variabel deformierten QRS-Komplexen ("chaotisches" EKG-Bild). Adenosin oder eine elektrische Kardioversion sind i.d.R. That’s where MAT gets its name. Atrial tachycardia time from a Holter recording was 44.2 minute/day before the caffeine load, compared with 215.2 minute/day during the caffeine load. 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). Betroffene Säuglinge sind wegen eines linksventrikulären Pumpversagens oft schwer krank und ggf. Typischerweise zeigen sich mindestens drei unterschiedlich konfigurierte P-Wellen (v.a. Multifocal atrial tachycardia (MAT) is a cardiac arrhythmia caused by multiple sites of competing atrial activity. multifocal atrial tachycardia: multifocal origin of tachycardia within the atrium; often confused with atrial fibrillation during physical examination. If a doctor finds MAT on an EKG, your pulse also may be fast and irregular. Table of Content … 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). 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. Multifocal Atrial Tachycardia (MAT) Multifocal Atrial Tachycardia (MAT) Overview. 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. Multifocal atrial tachycardia is typically seen in elderly patients with severe illnesses, most commonly COPD. Card Electrophysiol Rev. Costello-Syndrom). Verapamil is negatively inotropic and a vasodilator. Kidney stones - what to ask your doctor.

Bitte logge Dich ein, um diesen Artikel zu bearbeiten. Tags: 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 (MAT) is a type of irregular heartbeat in which the heart beats faster than it should. But this irregular heart rhythm will show up in an electrocardiogram (EKG). Doctors often find it unexpectedly in people with other health problems. Supraventrikuläre Tachykardie. Multifocal atrial tachycardia. Im Gegensatz dazu sind die meisten erwachsenen Patienten asymptomatisch, abhängig von der Frequenz kann es jedoch zu Dyspnoe, Palpitationen oder Schwindel kommen. In this type of tachycardia, those irregular signals come from three or more places in the heart’s upper chambers. Your doctor may recommend other treatments, such as beta-blockers or calcium channel blockers, depending on what other conditions you have. 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. It’s hard to tell from a physical exam if a person has MAT. A rapid, irregular atrial rhythm arising from multiple ectopic foci within... Electrocardiographic Features. Heart rate > 100 bpm (usually 100-150 bpm; may be as high as 250 bpm). Rate: 150-250P waves: VisibleQRS: Narrow Atrial Tachycardia is caused by an irritated site in the Atria. Multifocal atrial tachycardia is typically seen in elderly patients with severe illnesses, most commonly COPD. The human heart gives off electrical impulses, or signals, which tell it to beat. “Multifocal” means having more than one focus and “atrial” refers to the heart’s two upper chambers, called atria. 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 ]. Multifocal atrial tachycardia (MAT) is a cardiac arrhythmia caused by multiple sites of competing atrial activity. 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. It occurs when too many signals (electrical impulses) are sent from the upper heart (atria) to the lower heart (ventricles). Irregularly... Clinical Relevance. Electrical cardioversion has no effect. Doctors don’t know exactly what causes MAT. Treatments used by doctors to correct other arrhythmias usually don’t work to treat MAT. 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). Electrical cardioversion has no effect. Um diesen Artikel zu kommentieren, melde Dich bitte an. Multifocal atrial tachycardia (MAT) is a type of irregular heartbeat in which the heart beats faster than it should. MAT itself isn’t usually life-threatening. Verapamil is negatively inotropic and a vasodilator. Multifocal atrial tachycardia (MAT) is a cardiac arrhythmia which is specifically a type of supraventricular tachycardia with an irregular, rapid atrial rhythm arising from multiple ectopic foci within the atria with a heart rate exceeding 100 beats per minute. Magnesium and potassium therapy in multifocal atrial tachycardia. Part of the reason it’s poorly understood is that MAT isn’t a very common type of arrhythmia. It's generally seen in children with underlying heart disorders such as congenital heart disease, particularly those who've had heart surgery. Synonym(s): multifocal atrial tachycardia Without an EKG, it’d be hard to tell the difference between MAT and some other type of arrhythmia. 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. 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). Zur Abklärung der Ursache können laborchemische Untersuchungen und eine Echokardiographie sinnvoll sein. This happens when the upper chambers of your heart send too many electrical signals to … It’s one of many types of heart arrhythmias or irregular heart rhythms.

Carotid massage has no effect. Multifocal atrial tachycardia Multifocal atrial tachycardia is an unusual variant of ectopic atrial tachycardia. Multifocal atrial tachycardia (MAT) is a rapid heart rate. L), 80 percent ofpatients had ventricular premature beats (VPBs), 44 percent had paired VPBs, and 25 percent had ventricular runs. Ablation, cardioversion, pacemaker, and more. 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. In most cases, the best way to treat MAT is to treat the other health problems. Radiation therapy - questions to ask your doctor.

These problems may include: Sometimes MAT happens in people after major surgery. When your heart beats normally, there are between 60 and 100 beats per minute. The mechanism of the arrhythmia may be delayed afterdepolarizations leading to triggered activity, but this has not been firmly established. If you have an electrolyte imbalance, your doctor may start by trying to correct it. But it sometimes also happens in children or young adults. Ca++ channel blockers (verapamil.) The main cause of Multifocal Atrial Tachycardia is an abnormality in the signals which are being sent from the upper chambers of the heart which is the atria to the lower chambers of the heart which are the ventricles.
