What is a typical heart rate for junctional tachycardia?

Junctional tachycardia is characterized by a rapid heart rate that originates from the area of the heart known as the junction, which is located between the atria and the ventricles. A typical heart rate for junctional tachycardia generally exceeds 100 beats per minute, making the choice that indicates greater than 100 bpm the most accurate.

Understanding the condition involves recognizing that junctional tachycardia can occur when there is enhanced automaticity or reentry within the junctional tissue, leading to an increased heart rate. This increase means that patients may present with a heart rate typically ranging from 100 to 150 bpm or even higher, often classified as a form of AV nodal reentrant tachycardia.

The other heart rate ranges mentioned do not align with junctional tachycardia's hallmark characteristic of elevated rates. For instance, a heart rate less than 60 bpm reflects bradycardia, while the range of 60 to 100 bpm is typical for normal sinus rhythm rather than a tachycardia pattern. Consequently, recognizing that junctional tachycardia results in heart rates above 100 bpm is crucial for accurate diagnosis and management.
