For people with bradycardia, going to high altitude may be risky. Higher altitudes have lower oxygen levels, which can challenge the body with hypoxia. People with bradycardia can go to high altitudes if they do not have other heart conditions and have a heart rate between 60 and 100 beats per minute. However, it is recommended that an electrocardiogram (ECG) be checked before departure to see if the bradycardia is causing myocardial ischemia. If a person with bradycardia has other related illnesses or a heart rate below 60 beats per minute, it is recommended not to travel to high altitude areas because it may cause the heart to be unable to compensate for the low-oxygen environment, which may easily cause pulmonary fluid and result in life-threatening injuries.
In short, for people with bradycardia who want to go to high altitudes, they should consult a doctor's advice first and carry out the necessary physical checkups and preparations. At the same time, they should carry the necessary medical equipment and medicines to cope with possible physical discomfort and emergencies.
