SVT & WPW Syndrome — ECG Academy Lesson

Identify SVT on a rhythm strip by its sudden onset, rapid regular rate, and narrow QRS complexes. Understand AVNRT as the most common mechanism. Recognize the three ECG hallmarks of WPW (short PR, delta wave, wide QRS) and the critical danger of atrial fibrillation in WPW patients.

Learning Objectives

• Define SVT as an umbrella term and identify AVNRT as the most common mechanism
• Recognize SVT on a rhythm strip: sudden onset, rate 150-250, regular narrow QRS, P waves absent or buried
• Describe vagal maneuvers and adenosine as first-line treatments for stable SVT
• Identify the three ECG hallmarks of WPW: short PR, delta wave, and wide QRS
• Explain why AV nodal blockers are contraindicated in WPW with atrial fibrillation
• State the monitor tech actions for SVT and suspected WPW
