-==Hypercalcemia==
-Hypercalcemia, high blood calcium, speeds repolarization. Characteristics of hypercalcemia:
-*Mild: broad based tall peaking T waves
-*Severe: extremely wide QRS, low R wave, disappearance of p waves, tall peaking T waves.
-==Hypocalcemia==
-ECG-characteristics of hypocalcemia, low blood calcium:
-*Narrowing of the QRS complex
-*Reduced PR interval
-*T wave flattening and inversion
-*Prolongation of the QT-interval
-*Prominent U-wave
-*Prolonged ST and ST-depression
