Hypercalcemia — ECG Academy Lesson

Recognize the ECG changes of elevated calcium, especially shortened QT from ST-segment compression, and know when severe findings require urgent escalation.

Learning Objectives

• Identify shortened QT as the hallmark ECG finding of hypercalcemia
• Explain why elevated calcium compresses the ST segment
• Recognize severe calcium-related conduction changes and bradycardia
• Report hypercalcemia-pattern changes with useful clinical context
