D) 40 to 60

Question

Quizplus · Accepted Answer

The AV (Atrioventricular) node, when acting as the pacemaker, typically generates a heart rate of 40 to 60 beats per minute. This is slower than the SA (Sinoatrial) node but faster than the rates produced by the ventricles when they act as the pacemaker.

If the AV Node Were Forced to Assume Pacemaker Activity,the
