Multifocal atrial tachycardia (MAT) is an arrhythmia caused by atrial competition. It is characterized by an irregular atrial rate of more than 100 beats per minute (BPM). Atrial activity is well organized, with at least three distinct p-waves. Prior to 1968, MAT had been described in terms of tachycardia. In general, tachycardia can be improved by treating patients with underlying problems such as respiratory failure, sepsis, and theophylline poisoning. Tachycardia in this case is only temporary and can be resolved when the underlying disease improves. Keyword: multifocal atrial tachycardia
What if mat is in a 25 yr old that isn’t on any lung meds
This condition is often caused by conditions that induce hypoxia, such as lung problems. But this does not necessarily mean that all cases are caused by lung problems. There are other cases where a clear cause cannot be determined.
 
Your doctor will first treat the underlying cause of your MAT. That can include hypoxia, or inadequate oxygen, congestive heart failure, and theophylline toxicity.
You may receive therapies to improve your blood oxygen levels. If the problem is theophylline toxicity, your doctor will stop that medication. Magnesium and potassium may be given intravenously to treat MAT. Your doctor may also prescribe medications like certain beta-blockers or calcium channel blockers that have proved effective in treating MAT.

Individuals with uncontrollable MAT may benefit from atrioventricular ablation. This involves the surgical removal of the tissue that sends signals to the heart for it to beat and the permanent implantation of a pacemaker.
