There are also herbal medicines that can improve the heart rate, but they need to be prescribed by a professional Chinese medicine practitioner after the Chinese medicine diagnosis, after all, the prescriptions chosen are different for different patients and different types of evidence. For bradycardia, it is best to have a cardiac electrophysiological examination, such as an atropine test, or even a direct cardiac electrophysiological examination. In case of poor sinus node function or even loss of sinus node function, a pacemaker can be installed directly for treatment, after all, any medication is almost ineffective at this point. Of course, other causes of bradycardia need to be ruled out, such as hypothyroidism, and thyroid function should be corrected first, etc. If the bradycardia is physiological, such as athletes or people who often do heavy physical work or at rest, the heart rate may also be lower than 50 beats/min, and there is no need to treat it.
