What is a typical rate range for junctional tachycardia?

Explanation:
Junctional tachycardia is a fast rhythm that originates from the AV junction, so the ventricular activation is driven by automaticity or a reentry circuit in that area and the QRS is typically narrow. The rate reflects how quickly the AV junction is firing, and in many teaching contexts this pace sits in the lower tachycardia range, around 60–120 beats per minute. This range is fast enough to be considered tachycardia compared with a normal resting junctional rhythm (which is slower) but not as high as many atrial or AV-reentrant tachyarrhythmias that commonly reach well above 120 bpm. Therefore, 60–120 bpm is viewed as the representative rate range for junctional tachycardia.
