You need to consult your primary healthcare provider or your physician for clinical assessment and to find the cause of potassium loss from the body. Low potassium is known to have a deleterious effect on the heart thus, erratic heart beats that your wife is experiencing is probably due to low potassium levels. Correction of blood potassium levels will correct the potassium levels. Thanks and take care Chat Doctor.  </s>
