Can Low Electrolytes Cause Irregular Heartbeat

Substances in the blood called electrolytes — such as potassium, sodium, calcium and magnesium — help trigger and send electrical impulses in the heart. An imbalance in electrolytes — for example, if they are too low or too high — can interfere with heart signaling and lead to irregular heartbeats.

Do electrolytes help with irregular heartbeat?

Electrolytes help trigger and regulate electrical impulses in the heart and low levels of magnesium and potassium can lead to an electrolyte imbalance, which can contribute to arrhythmia.

Can dehydration cause irregular heartbeat?

Dehydration can cause heart palpitations. That’s because your blood contains water, so when you become dehydrated, your blood can become thicker. The thicker your blood is, the harder your heart has to work to move it through your veins. That can increase your pulse rate and potentially lead to palpitations.
