Do any health care professionals know if slightly low potassium can cause heart symptoms?

Sometimes. : By the time your blood potassium is low the total body potassium is really depleted. So it may take a while for levels to normalize. Slightly low potassium on it's own should not cause any arrhythmias. In combination with certain medications heart rhythm abnormalities may occur.
