Correct Answer is D

Explanation

A pacemaker sends electrical signals to the heart to regulate the heartbeat.
On an electrocardiogram (ECG), these signals appear as small spikes followed by a QRS complex, which represents the contraction of the ventricles.
Choice A, A regular sinus rhythm, is not the correct answer because a regular sinus rhythm is a normal heart rhythm that originates from the sinoatrial (SA) node and does not involve a pacemaker.
Choice B, A chaotic, irregular rhythm, is not the correct answer because a pacemaker is designed to regulate the heartbeat and prevent chaotic or irregular rhythms.
Choice C, the Absence of any electrical activity, is not the correct answer because a pacemaker sends electrical signals to the heart to regulate its activity.

A. Prolonged PR intervals. B. Nondiscernible P waves. C. More P waves than QRS complexes. D. No correlation between P and QRS waves.

Correct Answer is A

Explanation

First-degree heart block is a type of atrioventricular (AV) block that involves the consistent prolongation of the PR interval (defined as >0.20 seconds) due to delayed conduction via the atrioventricular node.
This is seen on an ECG as a PR interval greater than 200 ms in length.
Choice B: Nondiscernible P waves are not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice C: More P waves than QRS complexes is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice D: No correlation between P and QRS waves is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
