Accelerated Junctional & Junctional Tachycardia — ECG Academy Lesson

Differentiate accelerated junctional rhythm from junctional tachycardia, understand the causes — especially digitalis toxicity — and learn the appropriate monitor tech response for elevated junctional rates.

Learning Objectives

• Define accelerated junctional rhythm (60-100 bpm) and explain why it is "accelerated"
• Define junctional tachycardia (> 100 bpm) and distinguish it from other narrow-complex tachycardias
• Identify digitalis toxicity as the classic cause of accelerated junctional rhythms
• List additional causes including myocardial ischemia, post-cardiac surgery, and electrolyte imbalance
• Describe the monitor tech response to new-onset accelerated junctional rhythm or junctional tachycardia
