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. Low potassium levels can cause relatively stable arrhythmias, while high potassium levels can quickly lead to lethal arrhythmias. Sodium, magnesium and calcium imbalances also place the heart at risk for arrhythmias.
Abnormal levels of electrolytes (minerals) in the blood. Decreased potassium and/or magnesium are the most common associated abnormalities of electrolytes. Both may be caused by the use of diuretics (water pills), among other reasons. There are unusual congenital (familial) causes of ventricular arrhythmias.
