What is an Accelerated Junctional Rhythm?

A regular rhythm with a rate of 60-100 beats/min
A slow rhythm with a rate below 60 beats/min
An irregular rhythm with no discernible rate
A chaotic rhythm with varying beat rates

The correct answer is: A regular rhythm with a rate of 60-100 beats/min

An Accelerated Junctional Rhythm is characterized by its regular rhythm and a heart rate that typically falls between 60 to 100 beats per minute. This rhythm originates from the junctional area of the heart, specifically the atrioventricular (AV) node, and occurs when the rate of impulses generated by this area exceeds that of the sinus node. The correct understanding of this rhythm includes recognizing that, while a normal junctional rhythm has a rate below 60 beats per minute, the "accelerated" nature indicates a higher rate. Thus, the distinguishing feature is that it is regular, not chaotic or irregular, and maintains a consistent heart rate within the specified range. Understanding these parameters is essential for recognizing and interpreting cardiac rhythms effectively in patient care settings.
