Elderly people who are at rest with a heart rate of more than 40 times per minute have problems, relatively speaking, and can start by taking heart pills or Ningxinbao capsules to raise their heart rate. Be sure to ask the patient if he or she has taken certain drugs that slow down the heart rate. Such problems can also occur after an overdose, and this time the drug should be stopped or reduced and stopped. For example, some elderly people may just take Bisoprolol or Metoprolol in too large a dose, and they will have a slower heart rate. Some elderly people have a heart rate of more than 40 times per minute during deep sleep, which is relatively normal and does not constitute an abnormal problem and does not require further treatment. There are also some elderly people whose slow heart rate is actually caused by hypothyroidism, which should be combined with oral medication such as Eugenol, because when hypothyroidism improves, the heart rate will naturally return to normal levels. Some elderly people may have severe stenosis in their coronary arteries, which can be treated with coronary interventions to improve the bradycardia.
