Know the EKG abnormalities associated with different electrolyte abnormalities
Explanation:
We are all familiar with the EKG changes in different electrolyte abnormalities but because they are rarely found enlisted on a single page, we tend to forget them or get confused with them.
| Electrolyte abnormality | EKG findings |
| Hyperkalemia | Tall & narrow (peaked) T waves, loss of P waves & soon after, there is QRS widening |
| Hypokalemia | (Pseudo) QT prolongation by way of losing T wave & U wave becoming prominent. |
| Hypomagnesemia | Same as hypokalemia |
| Hypercalcemia | QT shortening (I guess because more calcium exists, the electrical events can take place quickly). |
| Hypocalcemia | QT prolongation. |
