High Potassium May Cause Heart Issues

Potassium is essential for cells to function properly.

High potassium is a level determined by a specific blood test:

  • Electrocardiogram (ECG) Potassium level

You may get a result that shows a high level of this mineral. It may make sense to repeat the test. If you repeatedly see higher levels, it's imperative to speak with your doctor.

High potassium levels are a problem in which the amount of potassium in the blood is higher than normal. The medical name of this condition is hyperkalemia. High potassium can create interference with muscle activity. If you feel a cramp in your leg or in another targeted area, this could be reason.

High potassium levels may cause heart issues such as:

  • Arrhythmia (irregular heartbeat or abnormal heart rhythm)
