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.
