Other test for hypermagnesemia diagnosed include:
Electrocardiogram: the emergence of conduction block and bradycardia. Hypermagnesemia showed the electrocardiogram PR interval prolongation, QRS widening and QT interval prolongation. Because of high blood magnesium often accompanied by hyperkalemia, it can be pointed T wave high.
B-ultrasound: early detection of organic changes in the kidney.
