Symptoms depend on many things, including: 1  Type and strength of voltage. 2  How long you were in contact with the electricity. 3  How the electricity moved through your body. 4  Your overall health.
Hyponatremia refers to a lower-than-normal level of sodium in the blood. Sodium is essential for many body functions including the maintenance of fluid balance, regulation of blood pressure, and normal function of the nervous system.
Hyponatraemia is the most common electrolyte disorder and is often an incidental finding on routine blood tests. Hyponatraemia describes a serum sodium concentration which is lower than normal (< 135 mmol/L). It is most commonly a result of excess water diluting the serum sodium levels in the body (e.g. as seen in congestive heart failure), but hyponatraemia can also exist with normal or decreased water levels.
