Doctors don’t know exactly what causes MAT. Costello-Syndrom). The human heart gives off electrical impulses, or signals, which tell it to beat. 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.' When your heart beats normally, there are between 60 and 100 beats per minute. [Article in German] Toussaint R, Hofstetter R, von Bernuth G. Four infants with multifocal atrial tachycardia are presented. 1997; 1 (1/2): p.71-75. It is characterized by an irregular atrial rate greater than 100 beats per minute (bpm). Multifocal atrial tachycardia: Diagnosis, Causes, Pathofisiology, and treatment – Tachycardia is a condition in which the heart rate exceeds 100 beats/minute. MAT itself isn’t usually life-threatening. 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 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 (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). Part of the reason it’s poorly understood is that MAT isn’t a very common type of arrhythmia. Verapamil is negatively inotropic and a vasodilator. Atrial tachycardia is the least common type of supraventricular tachycardia. beatmungspflichtig. 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 Bei Neugeborenen ist sie am häufigsten vorzufinden.

Multifocal atrial tachycardia (MAT) is a rapid heart rate. Sometimes MAT goes away and then comes back. Tachycardia can be categorized into two main types, namely supraventrikular or ventricular, where previously divided into narrow complex tachycardia and a wide complex tachycardia. Multifocal atrial tachycardia. Magnesium and potassium therapy in multifocal atrial tachycardia. 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. Im Gegensatz dazu sind die meisten erwachsenen Patienten asymptomatisch, abhängig von der Frequenz kann es jedoch zu Dyspnoe, Palpitationen oder Schwindel kommen. 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 … MAT usually happens in older people, with an average age of 70. If you have MAT that doesn’t go away, your doctor may consider whether surgery is an option. It occurs when too many signals (electrical impulses) are sent from the upper heart (atria) to the lower heart (ventricles). The following therapy can be applied (if the tachycardia due to MAT is causing hemodynamic issues.) “Multifocal” means having more than one focus and “atrial” refers to the heart’s two upper chambers, called atria. 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 type of irregular heartbeat in which the heart beats faster than it should. 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. 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. Your doctor may recommend other treatments, such as beta-blockers or calcium channel blockers, depending on what other conditions you have. If you have an electrolyte imbalance, your doctor may start by trying to correct it. The initial treatment of multifocal atrial tachycardia should include supportive measures and aggressive reversal of precipitating causes.

Treatment of the multifocal atrial tachycardia (MAT) Treat the underlying cause. In multifocal atrial tachycardia, several different foci activate the atria. In this type of tachycardia, those irregular signals come from three or more places in the heart’s upper chambers. 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. Carotid massage has no effect. These problems may include: Sometimes MAT happens in people after major surgery. People with MAT often need treatment in the hospital or intensive care unit (ICU). Anytime the heart beats faster than 100 beats per minute, it’s called a tachycardia (pronounced tak-ih-KAHR-dee-uh). Non-drug ways you can manage your condition. Causes.
