There are physiological factors (such as slow heart rate in athletes) and pathological factors (such as bradycardia and atrioventricular block), physiological factors generally do not need to be dealt with, and pathological factors can be treated with pacemaker implantation and medication. 1. Physiological factors: some young people in life, especially athletes, may have a heart rate lower than 50 beats per minute and vagal hyperexcitability, which is a kind of physical compensation without symptoms and does not need to be treated. 2. Organic diseases: if the patient suffers from congenital bradycardia, second degree type II or above atrioventricular block, slow heart rate may need pacemaker and other treatments, severe bradycardia can lead to cerebral ischemic attack, manifested as insufficient cerebral blood supply, sudden fainting and other symptoms. It can also be treated with medication, such as atropine. It is recommended that patients with a long-term heart rate below 50 beats per minute undergo ECG, cardiac ultrasound and other tests to assess the basic function of the heart, and they should consult a doctor in time, who will analyze the situation in a comprehensive manner and make a clear diagnosis.
