What defines junctional tachycardia?

Junctional tachycardia is defined as a rhythm that originates in the AV junction with a heart rate exceeding 100 beats per minute. This phenomenon occurs when the electrical impulse is generated in the area of the AV node, rather than from the atria or ventricles. This results in a rapid heart rate, distinctly over 100 bpm, which characterizes this specific type of tachycardia. In contrast, rhythms with a rate of 60-100 bpm, typically would not meet the criteria for tachycardia, as they are considered to be within normal limits. The mention of a long PR interval relates to atrioventricular block or other conditions rather than junctional tachycardia. Likewise, the absence of identifiable P waves occurs in various arrhythmias, but specifically, in junctional tachycardia, there may be potentially visible P waves occurring before or after the QRS complex, rather than being completely absent. Thus, option B directly aligns with the specific definition and characteristics of junctional tachycardia.
