Hypocalcemia — ECG Academy Lesson

Identify prolonged QT from ST-segment lengthening, distinguish it from potassium-related changes, and recognize the torsades risk of severe hypocalcemia.

Learning Objectives

• Identify prolonged QT with a lengthened ST segment as the hallmark of hypocalcemia
• Differentiate calcium-related QT prolongation from potassium- and medication-related patterns
• Explain why severe hypocalcemia increases torsades risk
• Escalate post-surgical and other high-risk hypocalcemia patterns promptly
