Question

question 3 of 20 what is the rhythm? select your answer. junctional rhythm ventricular paced rhythm (v - paced) atrial paced rhythm (a - paced) sinus bradycardia

Explanation:

1. In junctional rhythm, P - waves may be absent, inverted or precede QRS with a short PR interval. Here, there are no such distinct features.
2. In ventricular paced rhythm, pacing spikes precede wide QRS complexes. There are no pacing spikes before wide QRS in this tracing.
3. In atrial paced rhythm, pacing spikes precede P - waves which then precede normal QRS complexes. In this tracing, we see pacing - like spikes before P - waves and normal QRS following the P - waves, indicating atrial pacing.
4. Sinus bradycardia has normal P - waves, normal PR interval and a rate less than 60 beats per minute. This is not a slow - rate normal sinus rhythm.

Answer:

C. Atrial Paced Rhythm (A - Paced)
