Think hyperparathyroidism, sarcoidosis, thiazide use, bone remodeling. 🥛 Hypocalcemia: QT prolongs → torsades risk. Causes: hypoparathyroidism, PTH resistance, vitamin D deficiency, loops lose calcium. 🟦 Hypokalemia: Prominent U wave + T-wave inversion. Check for low magnesium too. 🔴 Hyperkalemia: Peaked T → then widene
