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.

What does MAT mean in cardiology?
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). The external structures of the heart include the ventricles, atria, arteries and veins.
What is MAT as in lung?
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 causes MAT?
Multifocal atrial tachycardia (MAT) is a supraventricular tachycardia resulting in a rapid, irregular atrial rhythm that is caused by multiple ectopic foci within the atria.
What is Mar rhythm?
A rapid, irregular atrial rhythm arising from multiple ectopic foci within the atria. Most commonly seen in patients with severe COPD or congestive heart failure. It is typically a transitional rhythm between frequent premature atrial complexes (PACs) and atrial flutter / fibrillation.
How does COPD cause MAT?
MAT is commonly precipitated by exacerbation of COPD, sometimes due to infection or cardiac decompensation. Increasing hypoxemia with respiratory acidosis and advanced disease also leads to increased bronchodilator usage, thereby increasing catecholamine levels, which may contribute to development of MAT.
Is MAT regular?
Multifocal atrial tachycardia (MAT) is a relatively infrequent arrhythmia, with a prevalence rate of 0.05-0.32% in patients who are hospitalized. It is predominantly observed in males and in older patients—in particular, elderly patients with multiple medical problems.
What are Bigeminal PVCs?
If you have bigeminy (bi-JEM-uh-nee), your heart doesn’t beat in a normal pattern. After every routine beat, you have a beat that comes too early, or what’s known as a premature ventricular contraction (PVC). PVCs are common and not always harmful. If you’re in good health, you may not even need treatment.
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.
What is sinus arrhythmia of the heart?
Sinus arrhythmia is a kind of arrhythmia (abnormal heart rhythm). For the most common type of sinus arrhythmia, the time between heartbeats can be slightly shorter or longer depending on whether you’re breathing in or out. Your heart rate increases when you breathe in and slows down when you breathe out.
What is the difference between sinus rhythm and arrhythmia?
Normal sinus rhythm is a regular rhythm found in healthy people. Sinus arrhythmia means there is an irregularity in the heart rhythm, originating at the sinus node.
What is the most common cause of sinus arrhythmia?
It’s not clear what causes people to develop a sinus arrhythmia. Researchers suspect that a connection between the heart, lungs, and vascular system may play a role. In older individuals, a sinus arrhythmia can occur as a result of heart disease or another heart condition.
Is sinus arrhythmia serious?
Sinus arrhythmia is a common, harmless condition that is not necessarily dangerous; however, it should be evaluated if accompanied by other signs of heart problems. Sinus arrhythmia is a variation in normal sinus rhythm.
How do you treat sinus rhythm?
Treatments for sinus tachycardia may include:
- reducing caffeine intake.
- quitting smoking and avoiding other sources of nicotine.
- exercising regularly.
- drinking enough water.
- consuming less than 2,300 milligrams of sodium per day.
What should a sinus rhythm look like?
When a person has a normal sinus rhythm on their EKG, these beats are in a regular, orderly rhythm. Each should look like the previous and will be as evenly spaced with each other. An EKG of a person with A-fib is very different in its appearance when compared with sinus rhythm.
What is a good heart rate when sleeping?
Average Heart Rates While Sleeping
During sleep, it is normal for a person’s heart rate to slow down below the range for a typical resting heart rate. Between 40 to 50 beats per minute (bpm) is considered an average sleeping heart rate for adults, though this can vary depending on multiple factors.
What is it called when your heart stops while sleeping?
Sleep apnea is a serious sleep disorder that happens when a person’s breathing is interrupted during sleep. People with untreated sleep apnea stop breathing repeatedly during their sleep, sometimes hundreds of times during the night.
What is a good resting heart rate for a 65 year old woman?
For most healthy adult women and men, resting heart rates range from 60 to 100 beats per minute.
