Potassium-Related ECG Patterns — ECG Academy Lesson

Recognize hyperkalemia and hypokalemia ECG changes, classify severity trends, and escalate patterns associated with ventricular instability.

Learning Objectives

• Identify hallmark hyperkalemia patterns and progression
• Identify hallmark hypokalemia patterns including U-wave prominence
• Differentiate repolarization changes likely related to potassium shifts
• Escalate potassium-related patterns when risk features are present
