How is the atrial rate typically categorized in wandering pacemaker rhythm?

• A. Below 60 bpm
• B. Between 60-100 bpm
• C. Above 100 bpm
• D. Irregular and inconsistent

Answer: (B)

The atrial rate in wandering pacemaker rhythm is typically categorized as being between 60-100 beats per minute. This rhythm occurs due to the shifting of the pacemaker activity from the sinoatrial node to other areas in the atria. Each area of pacemaker activity can generate impulses at different rates, but when averaged out, the atrial rate falls within the normal range.

In wandering pacemaker, the rhythm can be irregular, and the heart rate may fluctuate slightly based on which area of the atria is dominating at any given time. However, the atrial rhythm generally maintains a rate that is considered normal for clinical significance, allowing it to be categorized accurately. This categorization helps healthcare professionals assess the patient's condition and decide on any necessary interventions or treatments.
