Electrolyte imbalance

• Sodium problems —> CNS problems.

• Potassium (Kalium) problems —> Cardiac problems (i.e. arrhythmia).

  • Hypokalemia can lead to:

    • prominent U wave.

    • T-wave flattening.

    • ST-segment changes.

  • Hyperkalemia can lead to:

    • Peak T-wave.

    • Flattened P wave,

    • Deep S wave

    • Sudden cardiac death..
