What defines Accelerated Junctional Rhythm?

Accelerated Junctional Rhythm is characterized by a regular rhythm that occurs with a heart rate between 60 and 100 beats per minute. This arrhythmia originates from the junctional tissue, typically the area around the atrioventricular (AV) node, and often occurs due to increased automaticity of this junctional pace-making tissue.

The reason this definition is significant is that it distinguishes Accelerated Junctional Rhythm from other types of junctional rhythms. For example, junctional rhythms can also be slower or exhibit irregularities, which differentiates them from the accelerated variant where the heart rate is elevated but remains within a specific range.

Understanding the definition and characteristics of different rhythms allows healthcare professionals to effectively identify and manage cardiac conditions, making the ability to distinguish Accelerated Junctional Rhythm crucial in clinical practice.
