How does electrolyte imbalance affect the heart?

Electrolyte imbalanc: Can negatively effect your heart's rhythm and its ability to beat normally.

They Drive the Heart: Your heart is a muscular pump with four valves that will not do anything without the electrical impulses that drives it. Sodium (na+) potassium (k+) and calcium (ca 2+) are the primary electrolytes that are critical for a normal heart rhythm. The heart will beat abnormally (arrhythmias) if the electrolytes are not in their normal ranges. The kidneys do a pretty good job keeping a balance.

It can promote: Electrical disturbance or arrythmia.
