Which statement correctly defines the rate ranges for a junctional rhythm?

• A. Normal 60-100 BPM; Accelerated 40-60 BPM; Tachycardic > 120 BPM
• B. Normal < 60 BPM; Accelerated 60-100 BPM; Tachycardic > 100 BPM
• C. Normal 40-60 BPM; Accelerated 60-100 BPM; Tachycardic > 100 BPM
• D. Normal < 50 BPM; Accelerated 50-90 BPM; Tachycardic > 90 BPM

Answer: (B)

A junctional rhythm typically runs slower than a normal sinus rhythm, and its rate is categorized into three ranges: a normal rate under 60 beats per minute, an accelerated rate from 60 to 100 beats per minute, and a tachycardic rate over 100 beats per minute. The statement that describes normal as less than 60, accelerated as 60–100, and tachycardic as greater than 100 best matches the standard classifications used when interpreting AV-node–origin rhythms. The other options misstate where the normal range or the tachycardia threshold actually sits, which would lead to incorrect labeling of the rhythm.
