Calcium and Magnesium Patterns — ECG Academy Lesson

Quick overview of calcium- and magnesium-related repolarization changes before the detailed electrolyte lessons that follow.

Learning Objectives

• Preview the QT behavior patterns linked to calcium disturbances
• Preview the ventricular-instability risk context linked to magnesium depletion
• Recognize when repolarization changes need detailed follow-up in later lessons
• Communicate interval-risk findings using objective telemetry language
