What is MAT on an ECG?
Table of Contents
Multifocal atrial tachycardia — or MAT — is a rhythm that frequently occurs in the setting of severe lung disease. MAT is characterized by three different P-wave morphologies within one 10-second 12-lead ECG at a heart rate > 100 beats per minute.
What is a MAT rhythm?
Multifocal atrial tachycardia (MAT) is a cardiac arrhythmia caused by multiple sites of competing atrial activity. It is characterized by an irregular atrial rate greater than 100 beats per minute (bpm).
How is WAP treated?
In most cases, a wandering atrial pacemaker doesn’t require treatment. But you will need treatment if the condition is caused by digoxin toxicity. This is a potential side effect of digitalis therapy. Digitalis is a medicine used to treat some heart conditions.
What is the difference between MAT and WAP?
There is no thromboembolism risk in MAT, such as seen in atrial fibrillation or atrial flutter, as the atrium are contractile in MAT. If the heart rate is less than 100 beats per minute, then the rhythm is wandering atrial pacemaker, or WAP.
Is MAT regular or irregular?
Multifocal atrial tachycardia (MAT) is a type of irregular heartbeat in which the heart beats faster than it should. It’s one of many types of heart arrhythmias or irregular heart rhythms. When your heart beats normally, there are between 60 and 100 beats per minute.

Is WAP a regular?
Wandering atrial pacemaker (WAP) is an atrial rhythm where the pacemaking activity of the heart originates from different locations within the atria. This is different from normal pacemaking activity where the sinoatrial node (SA node) is responsible for each heartbeat and keeps a steady rate and rhythm.
What is supraventricular tachycardia (SVT)?
Supraventricular tachycardia (SVT) is as an abnormally fast or erratic heartbeat that affects the heart’s upper chambers. An abnormal heartbeat is called an arrhythmia. SVT is also called paroxysmal supraventricular tachycardia. A normal heart rate is 60 to 100 beats per minute.
What is the most common cause of SVT?
Age. Some types of SVT are more common in people who are middle-aged or older. Coronary artery disease, other heart problems and previous heart surgery. Narrowed heart arteries, a heart attack, abnormal heart valves, prior heart surgery, heart failure, cardiomyopathy and other heart damage increase your risk of developing SVT.
What is the difference between normal heart rate and SVT?
SVT is also called paroxysmal supraventricular tachycardia. A normal heart rate is 60 to 100 beats per minute. A heart rate of more than 100 beats per minute is called a tachycardia (tak-ih-KAHR-dee-uh). During an episode of SVT, your heart beats about 150 to 220 times per minute, but it can occasionally beat faster or slower.
What are the signs and symptoms of SVT in children?
In infants and very young children, signs and symptoms may be difficult to identify. They include sweating, poor feeding, pale skin and a rapid pulse. If your infant or young child has any of these symptoms, ask your child’s doctor about SVT screening.
