Which of the following indicates an accelerated junctional rhythm?

An accelerated junctional rhythm is characterized by a heart rate that is between 60 and 100 beats per minute. This rhythm originates from the junctional tissue (the area at the junction of the atria and ventricles) and occurs when the inherent pacemaker of the heart in the junctional area becomes more dominant than the sinus node. In this case, the rate falls within the specified range, which aligns precisely with the definition of an accelerated junctional rhythm.

The presence of P waves can vary in junctional rhythms, often leading to their absence or alteration in morphology, but the defining factor of an accelerated junctional rhythm primarily hinges on the heart rate. Thus, the correct understanding of the characteristics that define accelerated junctional rhythm centers on this heart rate range.
