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. |
