You will get magnesium through your IV if you have moderate to life-threatening hypomagnesemia.

Telemetry monitoring:

This test is also called an EKG or ECG. Sticky pads are placed on your skin and attached to a monitor. Caregivers will record your heart's electrical activity to monitor for irregular or fast heartbeats.


  • Blood tests will show the level of magnesium in your blood.
  • A 24 hour urine test will show the amount of magnesium leaving your body through your urine. You will need to collect all of your urine for 24 hours. You will urinate into a container and then put the urine into a jug. The jug will need to be kept cold. At the end of 24 hours, the urine will be sent to a lab for tests.


Intravenous magnesium can cause skin redness, low blood pressure, and slow and irregular heartbeats. If not treated, hypomagnesemia can cause low calcium and potassium in your blood. It can also increase your risk for diabetes by preventing insulin from lowering your blood sugar levels. You may also be at risk for hardening of the arteries and other heart problems, such as fast and irregular heartbeats, which can be life-threatening.
