An atrial arrhythmia that occurs when the pacemaker role switches from the SA node to the atria and back again is called:
A)Atrial Tachycardia.
B)Wandering Pacemaker.
C)Atrial Flutter.
D)Atrial Fibrillation.

Question

Quizplus · Accepted Answer

This is known as a "Wandering Pacemaker" where the pace of the heartbeat alternates between the SA node and the atria. Atrial Tachycardia is a fast heart rate originating from the atria, Atrial Flutter is a rapid and regular contraction of the atria, and Atrial Fibrillation is an irregular and often fast heartbeat originating from multiple areas in the atria. These arrhythmias do not involve a switch between the pacemaker roles of the SA node and the atria.
