Monomorphic vs Polymorphic VT — ECG Academy Lesson

Distinguish fixed-shape from changing-shape VT, recognize Torsades de Pointes, and communicate the subtype clues that matter most during escalation.

Learning Objectives

• Define monomorphic VT and describe its visual appearance on a rhythm strip
• Define polymorphic VT and explain why QRS morphology varies beat to beat
• Recognize Torsades de Pointes by its characteristic twisting axis pattern
• Explain the relationship between prolonged QT interval and Torsades de Pointes
• Describe why monomorphic and polymorphic VT should be communicated differently in handoff
