According to the American Heart Association, potassium imbalances are the most common electrolyte-associated cardiac arrhythmias. Potassium plays a role in both nerve conduction and the heartâs ability to send an electrical impulse.

Sodium, magnesium and calcium imbalances also place the heart at risk for arrhythmias.
