Which of the following patient populations is multifocal atrial tachycardia (MAT) commonly seen in?

• A. Diabetic patients
• B. Patients with COPD
• C. Heart failure patients
• D. Pregnant women

Answer: (B)

Multifocal atrial tachycardia (MAT) is commonly associated with patients who have underlying conditions that can lead to changes in atrial structure and function. One of the most notable populations in which MAT is frequently seen is individuals with chronic obstructive pulmonary disease (COPD).

Patients with COPD often experience hypoxia and can have increased atrial stretch due to pressures in the lungs and changes in hemodynamics related to respiratory status. These factors can contribute to the development of atrial arrhythmias, including MAT, as the atria may have multiple ectopic foci firing due to the altered electrophysiological properties of the atrial tissue.

This distinct association with COPD sets it apart from other patient populations where MAT may not be as prevalent or may be influenced by different underlying mechanisms. Understanding this connection helps in recognizing and managing MAT effectively in the context of COPD.
