Magnesium Imbalances — ECG Academy Lesson

Recognize low-magnesium patterns that overlap with hypokalemia, identify high-magnesium conduction slowing, and escalate torsades-risk or infusion-related rhythm changes promptly.

Learning Objectives

• Recognize the ECG overlap between hypomagnesemia and hypokalemia
• Explain the magnesium-potassium relationship in refractory electrolyte abnormalities
• Recognize conduction slowing and bradycardia patterns in hypermagnesemia
• Recognize when prolonged QT plus ectopy creates a torsades-risk pattern that requires immediate escalation
