Sinus Tachycardia — ECG Academy Lesson

Recognize sinus tachycardia as NSR with a rate above 100 bpm, understand that it is a physiologic response rather than a primary arrhythmia, and learn to differentiate it from other causes of tachycardia.

Learning Objectives

• Define sinus tachycardia as NSR with a rate exceeding 100 bpm
• Explain why sinus tachycardia is a response to an underlying condition, not a primary arrhythmia
• List at least six common causes of sinus tachycardia
• Describe the key distinction between sinus tachycardia and atrial flutter with 2:1 block at a rate of 150 bpm
• Identify the monitor tech actions for sinus tachycardia
