Wandering atrial pacemaker

A wandering atrial pacemaker causes an arrhythmia that originates from several sites within the atria. This causes a rhythm that is slightly irregular with multiple different P wave shapes.

This rhythm is also known as Multifocal Atrial Tachycardia if the rate is fast (>100 bpm).
