For example, if the bradycardia is caused by endocrine metabolic diseases such as hypothyroidism, the patient can take thyroid hormone tablets such as eugenol to treat the bradycardia. In addition, drug-related factors, such as overdose of beta-blockers, can also cause bradyarrhythmias, which can be relieved by stopping the application of these drugs. If a patient has a slow arrhythmia due to organic heart disease, atropine or isoprenaline can be used to increase the heart rate, or the Chinese medicine Xin Bao Wan can be taken, which also has some effect. If the heart rate is below 40 beats per minute or slower, a pacemaker may be considered for treatment.
