What does "MAT" stand for in the context of ECG interpretation?

• A. Multifocal Atrial Tachycardia
• B. Measured Atrial Translation
• C. Myogenic Atrial Tachycardia
• D. Mixed Atrial Tachycardia

Answer: (A)

In the context of ECG interpretation, "MAT" stands for Multifocal Atrial Tachycardia. This arrhythmia is characterized by the presence of multiple ectopic foci within the atria, which means that the atrial impulses originate from various locations rather than a single point. This condition typically presents with a heart rate that exceeds 100 beats per minute and shows distinct P waves that may vary in morphology, reflecting the different sites of impulse generation. Patients with MAT often have underlying conditions such as chronic obstructive pulmonary disease (COPD) or are experiencing significant physiological stress. The identification of MAT on an ECG is crucial because it can guide treatment strategies that may include addressing the underlying cause, controlling the heart rate, or managing symptoms.
