Question

Which of the following statements about Multifocal Atrial Tachycardia (Wandering Atrial Pacemaker) is accurate?

A) It is a type of neurological disorder.
B) It is a benign condition and does not require medical attention.
C) It is an abnormal heart rhythm characterized by multiple P-wave morphologies and an irregular heart rate.
D) It only affects the atria of the heart, leaving the ventricles unaffected.

Answer 1

Multifocal Atrial Tachycardia is an abnormal heart rhythm characterized by various P-wave morphologies and an irregular heart rate, indicating multiple ectopic foci in the atria.

Step-by-step explanation:

The accurate statement about Multifocal Atrial Tachycardia (MAT), also known as Wandering Atrial Pacemaker, is C) It is an abnormal heart rhythm characterized by multiple P-wave morphologies and an irregular heart rate. MAT involves the presence of at least three different P-wave morphologies in the same ECG lead, which indicates that the impulses are originating from multiple ectopic foci within the atria. While the atria are affected by this condition, it does lead to irregular conduction to the ventricles, so statement D is partially incorrect. It is not a neurological disorder but a cardiac arrhythmia, and it can often require medical attention to manage symptoms or underlying causes, thereby making statement B incorrect as well.
