What is the heart rate of a patient who is experiencing accelerated junctional rhythm?

40-60/min
60-100/min
100-120/min
120-160/min

The correct answer is: 60-100/min

Accelerated junctional rhythm is characterized by a heart rate that typically ranges from 60 to 100 beats per minute. This rhythm originates from the junctional area of the heart, which includes the AV node and surrounding tissue, and occurs when the heart’s intrinsic pacemaker, the SA node, is not functioning optimally. In this case, the junctional rhythm takes over, resulting in the heart beating at a faster rate than what would be classified as a normal junctional rhythm (which occurs at 40-60 beats per minute). When evaluating the possible heart rates for this rhythm, the definitive hallmark is that it accelerates beyond the typical junctional range up to a maximum of about 100 beats per minute, which classifies it as "accelerated." This differentiation is important in the context of diagnosing arrhythmias and determining the appropriate treatment for patients experiencing this condition.
