ECG Changes in Electrolyte Imbalances (Part 4) | Hyperkalemia, Hypokalemia, Calcium & More

Electrolyte imbalances and how they distort the ECG Welcome to Part 4 of our ECG Series In this video, you’ll learn to recognise the classic (and dangerous) ECG patterns caused by abnormal potassium, calcium, and magnesium levels. We’ll cover: Hyperkalemia – from peaked T waves to sine wave arrest Hypokalemia – U waves, ST depression, and arrhythmia risk Hypercalcemia -- (short QT, Osborn waves?) Hypocalcemia (long QT, T wave flipping) Magnesium (hypomagnesemia → torsade de pointes) – short vs. long QT, and why it matters Magnesium – its role in refractory arrhythmias We’ll also share clinical pearls to help you differentiate mimics and remember key findings for exams (USMLE, NCLEX, NURSING, PARAMEDIC) and real-world practice. 📌 Missed the earlier parts?
