If the patient has a feeling of weakness and panic, it is highly likely to be caused by hypokalemia or hypothyroidism. It is recommended to take an electrocardiogram and measure heart rate and blood pressure during the onset of discomfort. Further, thyroid function, serum ions and blood tests can be performed to rule out anemia. Patients with hypokalemia may be advised to take oral potassium chloride extended-release tablets. If it is caused by hypothyroidism, the patient is advised to take oral thyroid hormone tablets. If no abnormality is found after examination, it cannot be ruled out that the discomfort is caused by neurasthenia or disturbance in the regulation of the plant nerves. It is recommended that the patient can take drugs like Astragalus Yikki Drops to improve the symptoms of lack of energy. If the patient’s current blood pressure is not low and his heart rate is fast, he can also take Betaxolol or Bisoprolol in combination to improve the symptoms of heartburn.
