Get the facts on multifocal atrial tachycardia, a type of heart rhythm problem in which the heart beats too fast due to certain problems with the heart’s electrical system.

Multifocal atrial arrhythmia is an uncommon type of tachycardia that usually develops in people with certain illnesses. Those with the condition have a heart rate of over 100 beats per minute.

The arrhythmia is atrial fibrillation. There are two premature ventricular contractions (PVCs) (*) — complexes 2 and 6 — with the same morphology; ie, they are unifocal PVCs.

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 ...
