In which atrial dysrhythmia does the pacemaker site shift between the SA node, other sites in the atria, and/or the AV junction?

Question

Quizplus · Accepted Answer

A wandering atrial pacemaker is characterized by the pacemaker site shifting between the SA node, other sites in the atria, and/or the AV junction. Multifocal atrial tachycardia is characterized by at least three different P-wave morphologies in the same lead and a heart rate of greater than 100 beats per minute. Premature atrial complexes are early depolarizations of the atria resulting in a premature P-wave. Atrial fibrillation is characterized by a rapid, irregular atrial rhythm without discernible P-waves.
