Quizplus · Accepted Answer

Sinus rhythm is a normal heart rhythm in which the electrical impulse that triggers each heartbeat originates in the sinoatrial node (SA node), which is located in the right atrium. In Figure 4, the P waves are upright and occur regularly, indicating that the electrical impulse is originating in the SA node. The PR interval is normal, and the QRS complex is narrow, indicating that the electrical impulse is being conducted normally through the atria and ventricles.
