Question

Quizplus · Accepted Answer

Multifocal atrial tachycardia (MAT) is the rhythm most often associated with chronic obstructive pulmonary disease (COPD). MAT is characterized by an irregular, rapid heart rate with at least three different P wave morphologies on an ECG. It is believed to be caused by hypoxia and increased sympathetic tone in patients with COPD. Atrial fibrillation and sinus arrhythmia may also be seen in patients with COPD, but they are not as strongly associated with the condition as MAT. SVT is a narrow complex tachycardia that is not typically associated with COPD.
