What is the typical heart rate classified as junctional tachycardia?

Junctional tachycardia is characterized by a heart rate that typically exceeds 100 beats per minute. This condition arises from an increased firing rate of the junctional tissue, which is part of the conduction system of the heart. When the heart rate is categorized as junctional tachycardia, it usually ranges from 100 to 180 beats per minute, indicating that the heart is beating faster than normal.

The definition of tachycardia involves a heart rate greater than 100 beats per minute, which aligns with the specified characteristics for junctional tachycardia. The role of the junction or AV node in this type of tachycardia is crucial because it can take over when the SA node fails to initiate a proper rhythm or when bradycardia is present.

In summary, junctional tachycardia is identified by its heart rate consistently above 100 beats per minute, reflecting the increased automaticity of the junctional area of the heart.
