For people with slow heartbeat, going to high altitude may be risky. The low oxygen content at high altitude will pose a challenge to the human body. People with bradycardia can go to high altitude areas if they have no other heart diseases and their heart rate is between 60 ~ 100 beats per minute. However, it is recommended to check ECG before departure to see if bradycardia leads to myocardial ischemia. If people with bradycardia have other related diseases, or the heart rate is lower than 60 beats per minute, it is recommended not to go to high altitude areas, because this may cause the heart to be unable to compensate for the hypoxic environment, which may easily lead to edema and life-threatening.
In short, for people with bradycardia, if they want to go to high altitude areas, they should first consult a doctor and make necessary physical examination and preparation. At the same time, you should bring the necessary medical equipment and medicines to deal with possible physical discomfort and emergencies.
